Everything starts and ends with VPX
I don't have any VP8 tables on my cabinet and very few VP9's. I do have a couple of Physmod5 tables like AC/DC and Avengers (That one is actually Physmod2) but for the most part all my table recreations are VPX. The uptick in table releases has been quite noticeable in the last 12 months or so as VPX has really taken off. It is actively developed with the current version being 10.2. There is also some great work being done with vpinmame and being able to emulate modulated lighting with recent releases of Star Trek LE and TWD LE.
Physics wise I find VPX to play better than any other emulators, I do not like the way Future Pinball plays at all, granted I haven't invested a lot of time in getting it completely dialled in but I've read enough to give me confidence that even perfectly dialled in it is an entirely different experience than VP and one that I don't believe I will enjoy.
Other emulators to consider... Pinball FX2 would be one. That one is on my cabinet, it isn't trying to be a pinball emulator I don't find, it knows what it is and, which is a video game and I think it does a pretty good job at it. There are a couple of Unity tables out there, that I tried once, if you are only planning on running 30 tables though I wouldn't bother with them... there is also Time Shock from ProPinball (
http://www.pro-pinball.com/), it is just a single table but has cabinet support. I've purchased it but haven't gone back to dialling it in, I need to do that.
Edit: I didn't mention The Pinball Arcade. I haven't played a table on TPA that also exists in VPX that I like better. I love TPA on my iPad, but on my cabinet VPX is just a better emulator.
