One of the best things with software is that you can always
try before you buy, so do it and make good use of it! Adobe offers 30 free days for Lightroom and Photoshop, available separately—you can try Lightroom for a month until it expires, then try Photoshop. If you don’t like either of them you can revert to other options, even the software your camera manufacturer provides. If it’s a recent Sony camera, you may have gotten a free copy of Phase One’s Capture One Express. If it’s a Samsung camera (or, if you’re a wealthy man, a Leica), you may have a free copy of Lightroom; it could be the older version (Lr 5), which is still an excellent Raw editor and converter.
You absolutely don’t need more than the $10/month Creative Cloud Photography Plan to edit your Raw files—you can do a lot with much less, even free. This subscription plan lets you use the most popular photo editing and workflow management applications out there. Adobe is not a monopoly in this field—there are excellent Raw converters from Phase One, DxO Labs and others, some may do a better job than Adobe’s converter—but it sure feels like it is.
I would go for the $10/month plan.
Adobe no longer sells Photoshop as traditionally licensed software where you pay one price to buy it and own it forever. That ditched that many months back (it may be almost a year by now.) They will still sell you Photoshop Elements that way -- but not the full-blown version of Photoshop.
Adobe will license Lightroom as a buy-once model, but they aren't adding anything to that particular version of the Lightroom. Only the Lightroom CC (cloud) version gets updates.
When you pay the $10/month plan you get both Lightroom and Photoshop CC versions and all updates. Adobe calls this "cloud" software (it isn't "cloud" software, it's "subscription" software. There is a difference and Adobe doesn't offer anything that makes the software qualify as "cloud" but since "cloud" is getting a lot of attention in the computer industry lately, marketers love to slap the word "cloud" on something to help it sell.)
Basically for $120/year you get Photoshop CC, Lightroom CC, Lightroom Mobile, and a tiny bit of cloud-drive space (not enough to keep all your photos there, but enough to transfer your photos around between devices.) The cloud (subscription) license allows you to install the software on TWO computers (presumably you own them both). I use it on my desktop (iMac) primarily, but when I travel, I have a copy on my laptop (even though I prefer to use my desktop with a significantly larger and better display) so that I can process images when I'm away.
I have a friend who bought the non-cloud based version (Lightroom 6) and he's already starting to notice that Adobe has offered some updates to Lightroom CC that he won't be able to get.
Indeed, the Creative Cloud plan is a great value. You get a year’s use of the excellent tools it offers—latest version of Lightroom, latest version of Photoshop, Lightroom Mobile, etc.—for less than the price of Lightroom 6. One of the things I’ve been most impressed with is the Dehaze slider added to Lightroom CC and Adobe Camera Raw in the Photoshop CC update. At first I thought it wouldn’t really make a difference for me, as I’ve been dealing with haze successfully with a combination of the Blacks and Clarity sliders and the graduated adjustment filters, but oh my, I get even better results with it, and I’m only moving one slider!
We have to give credit where credit is due: Adobe has been very clear since they launched Lr CC and Lr 6, that only CC subscribers will get feature additions and updates on a regular basis, while Lr 6 buyers will have to wait for a major release that may come in the unforeseeable future (Lr 7). There were no surprises there, and it wasn’t just small print. Anyone who bought Lr 6 and is frustrated with Adobe not updating it with the CC features, just didn’t do their research before purchasing it. Not saying that’s the case with the situation you mentioned with your friend—after all, you didn’t say he is frustrated or disappointed at that.
