No, nothing against Cubase for any of the reasons given, but whatever choice one makes, there are compromises to be made. Personally I have been using using Reaper for ... well, even longer than that, and 'trialed' it for nothing for well over a year. I did finally decide to buy a license, but it has worked out to be less than the price of a cup of ordinary coffee per year (although, to be fair, I never drink coffee anyway, so...).
No, the main concern is having software that your 'platform' can support (I've never been one for acquiring 'cutting edge' stuff; all my 'puters have always been very low spec...), having a 'workflow' that makes sense (I have found it fairly easy to do easy stuff with any DAW, and I only do easy stuff, so...), and having the flexibility to be able to handle the very divers media and methods dictated by one's Muse. For me, Reaper does all of this; others have great success with other stuff. There's a reason why Cubase, Protools, GarageBand et al are used so widely, and for so long. They're all good; one just has to choose whichever ticks the most boxes, and accept whatever this choice implies. Reaper does all I need; there are many DAWs out there, including many fine free or low-cost ones.
Be aware, too, that Kontakt (even the Player version...) and Vsts in general, are a rabbit hole; it's often a Good Idea to have some kind of brake on one's aspirations, lest one falls into the 'All the gear, no Idea' trap. I'd be embarrassed to explain how I came to know this.
Hope this helps.
