Mike's and Quarter Arcade have the higher quality 60-in-1's if you end up going that route. I don't have experience with other games on the 60-in-1's, but I've played Donkey Kong on the icade 60-in-1's at a couple different locations, and while they are very good, there is a slight bit of lag to them. Probably not noticeable to most, but to those of us that have poured countless hours into playing on a legit PCB, it takes a bit of adjustment to get into a groove with the slight bit of delay.
I mean, it's probably a matter of a couple frames, but again, I notice it.
Maybe I'm crazy tho.
All that is to say, if you're wanting the wider selection of titles and don't think what I've said will be an issue, then 60-in-1 is probably the best option. If the wider selection of titles isn't that attractive and you prefer authentic feel, then go with a switcher.
