You can't "favor both", that doesn't make sense, especially when you follow up with "I lean towards portability".
Anyways, I favor power and price. I don't really think the portability enhances my Switch experience that much, it probably does for others though.
Sure I can. It depends on the game in question and if I am traveling or not. Right now, I favor Switch as I am traveling over the next few weeks. But when God of War came out, I favored my PS4 as I was at home most of the time.
I lean towards portability however because more often than not, the Hybrid nature of the Switch gives me more overall playtime without the hassle of remote play.
