I think you may know best as you are playing with a free trial on your laptop. I personally use LR but that is because I started with it from version 1 and grown used to it. I tried Luminar 3 but seen very little benefit over LR.

I am a bit of a fan of the subscription model for a few reasons. One is you have the choice to quit any time you want to, second is it is constantly updated with new functionality.

It would seem most software is heading that way.
