I am a long time Elements user, going from version 7 to 11 to 14, and have found that I can do very nearly everything in Elements [PSE] that others talk about in Lightroom [LR]. Nevertheless, recently members of my camera club "shamed me" into trying LR, which I did via the PS/LR Cloud package. I got it at a bargain price of $100 for the first year. Not much different in it, EXCEPT that I can now shoot and process RAW images, whereas before, I was limited almost exclusively to JPEG. With both LR and PSE now in hand, and with the capability of processing RAW, I've found that many of my images come out better, especially when the ambient light is less than satisfactory . For me, the combination of both fills the bill nicely, and I'd recommend it to you.
BTW, one of the benes of the Cloud pkg is that as soon as updates are developed, you get them automatically. In the 10 months I've had it, I've already gotten two updates, so not so bad. Everybody was upset when Adobe went to the Cloud "rental" system, but it turns out to be not as bad as everyone, including me, originally thought.
Good luck in your decision making and happy shooting!
