The answer depends on "what" you enjoy shooting. The 70D is the most versatile so if money is no object (but usually money is a factor in these decisions) then the 70D would win on a simple comparison of capabilities.
The 70D is Canon's latest "mid-range" DSLR. It's in a category above the Rebel bodies (entry level bodies), but not quite a high-end or pro category body.
When the 70D was initially released, the Canon 7D was probably the most popular camera for sports & action (excluding the 1D X -- Canon's flagship camera) because it had several features optimized for fast action photography. In continuous shooting mode, it can blast out 8 frames per second. Also, it has a 19 point auto-focus system in which every point is a "cross type" point (cross-type points are more accurate and difficult to trick into missing focus.) Usually Canon doesn't like to release camera bodies that have features which are either better than or equal to ... or even nearly equal to... a higher-end camera body. So some of the features on the 70D were a bit of a surprise...
The 70D can shoot 7 frames per second in "continuous" mode... just 1 frame per second slower than the 7D.
The 70D also has what appears to be the same 19 point auto-focus system as the 7D (the only difference I could find is that it doesn't support true "spot" focus mode in which you can pick an AF point but reduce the coverage area (suppose you're trying to shoot a subject using exceptionally narrow depth of field and you want to focus on the eye, and want to make sure the camera isn't tricked into focusing on something very close... such as the eyebrow... you might want to "reduce" the size of the are being used by the AF point.
This made people wonder if the 7D wasn't finally about to be replaced (Canon would typically only let the 70D have these features if they felt the 7D was not going to be threatened by it)... and sure enough Canon released the 7D II (with significant performance upgrades.)
The Rebel bodies don't get any weather-sealing treatment, but the mid-range bodies do. The caveat with "weather sealing" is that it's not water-proof. The seals won't keep water out if that water is under pressure or force. Getting splashed or rained on isn't a problem... submerging in water is a problem. Also... most lenses are _not_ weather sealed, but some are. Many (probably even most) but not all Canon "L" series lenses are weather-sealed. If you have a weather-sealed camera body but are using lens which is not weather sealed... well there's that saying about the "weakest link" -- you'd still need to stay away from water.
The 70D does have a newer sensor and it's slightly higher resolution. It very fractionally improves on dynamic range (by about 1/4 stop). If you were to compare this to, say, a Nikon D7100... that camera has very slightly fractionally better dynamic range still (about 1/2 stop better than a T5i or about 1/4 stop better than a 70D). It's not a huge difference (and, in my opinion, not enough to sway my choice given that there are a lot of other area that get my attention first.)
The 70D does have WiFi. I don't think of this as a big deal. Technically you can transfer images from your camera to your computer via WiFi (but considering it's probably faster to just eject the memory card and plug that into the computer... I'd much rather do that.) But one thing you can do via WiFi is remote control of the camera using a smart-phone (assuming you have a smart-phone.)
One thing I do find significant about the 70D is that it has a control layout more like a high-end body. There's a top LCD screen with several instant-access buttons to commonly adjusted features that you need to use menus to access on a Rebel body.
Also significant in the layout difference is the rear-dial. Rebel bodies get a front dial. The latest Rebel T6s gets a tiny top LCD and rear-dial, but the rest do not get a rear dial. I use the rear-dial on my camera extensively.... when shooting in manual mode, the front dial (by the shutter button) controls the shutter speed and the rear dial controls the aperture. In Tv or Av mode, the front dial controls the shutter or aperture setting you want to use and the rear-dial controls exposure compensation. On a Rebel body you have to use menus to make those adjustments, but the high-end bodies let you control those features on-the-fly without taking your eye away from the viewfinder to read menus or look for buttons. It's well-placed so that your index finger controls the front dial and your thumb controls the rear dial.
So overall... yes, the 70D is clearly a "better" camera in pretty much every way (performance, shooting speed, sensor, body layout, features, build quality, etc. etc.) Of course... it does cost more.
