MTR and VVR are substantially different experiences; I personally have only experienced MTR, but talked to a lot of folks that went to VVR.
I was at MTR in June before it was open for guests, but unless you book (I would guess expensive) rooms there in advance I don't think your experience would be much different. You pick up your plastic bucket, they give you a picnic table to spread out on to get your resupply into your pack, and there's a hose there you can get water from. There's a little store with limited things at high price.
Don't get me wrong, the people are really nice, it's just that their primary focus is on guests staying there.
The upside is that it's a small detour from the trail both in terms of time and distance. I didn't go to the hot springs so can't comment on those.
VVR has tent-cabins and I think they let hikers spend their first night there free. You can indeed get a meal there and the folks I've talked to all enjoyed it a lot, though some with chagrin at how much money they ended up spending — nice meals and beer etc but at a cost.
As you said, I went for MTR partly because it was about a day closer than VVR (about 21 trail miles), and its location was better to more evenly spread out stops both from where I was coming from (NOBO), and for a next-resupply at Mammoth Lakes. Most thru-hikers I know chose VVR anyway, and some went even longer without resupply to get there, starting from Kennedy Meadows (I resupplied in Independence). You just have to choose based on whichever factors are more important to you. My experience was faster, less distance, but with no social or meal options. That was okay as I got plenty of both in Mammoth Lakes.
