If you do decide to buy the game, get it on PC (and play with a controller). 60 fps, instant magic casting, and other stuff can make the combat feel a lot more fluid and responsive than on <30fps consoles.
I personally enjoy the combat, as I mainly play with a magic focussed character. I feel the frustrations mostly come from sword focused console users.
Further to this, it's worth noting that virtually the entire combat loop and its constituent mechanics are exposed in the player scripts and can be changed by rewriting portions of said scripts.
For instance, you can make changes to the soft lock functionality (which incidentally governs whether Geralt will perform a "long-winded" attack -- this can be modified so that the player decides whether to fire a near or far light attack) and you can make other changes such that the player can control when the combat stance is entered/exited.
For individuals who are unconcerned with non-canonical (from CDPR's perspective) balance/lore changes, you could, for instance, make changes to the damage modifiers so that enemies aren't enormous damage sponges on high difficulties or heavily nerf quen (as quen really only existed in the book lore as heliotrope and worked dramatically differently).
Now to be sure, it's unrealistic to expect everyone to do this, but if you have the inclination and the aptitude and have certain specific complaints about the combat system, well, chances are pretty good that you can change it to your liking.
