Hardware wise my opinion hasn't changed. It's great as a handheld, and relatively depressing for me as a home console. Unfortunately the latter is how i'd almost exclusivity be using it, so it's hard for me to be particularly enthusiastic.
I will get one eventually for its exclusives, and i don't doubt i'll enjoy them, but i expect i'll always feel a bit irritated that i have to play them on something so far behind almost everything else i use. My feelings towards the standard PS4's hardware have slowly shifted towards the negative (currently at "eh, could be worse"), and that was half~ a generation ahead of a docked Switch 3+ years ago.
It's not all negative though. As poor as it might be for me as a home console, it's still a colossal leap over the 3DS. Until now I've had to play a lot of my favourite series (e.g. Pokemon) with genuinely poor graphics, on a tiny screen, and in a fashion I've grown to dislike. The Switch significantly improves the first of those, and makes the latter two irrelevant. I doubt i'll ever properly like the Switch as a system, but i'll appreciate what it does for me with handheld IP.
