The Joust one would be my preference. The things that would negatively impact the comfort, would be poor height/ergonomics.
That first one, looked like the joy is angled vertically?! The second has more comfortable controls, but is just ugly to me. Might as well have a standup at that point.
The other issue I recall was the controls being nested uncomfortable under plexiglass on some.
I've been musing about making a cocktail cabinet someday though. The design is nice because it can potentially sit against a wall, throw a cover over the top and you have a 'table'. The downside to that is...most horizontal surfaces will accumulate clutter in no time. Which means you have to remove all the "stuff", if you want to play games. Which likely means you ended up with a an expensive table. On the plus side, it could be a great way for me to have a cab with some dedicated vertical games, and/or controls. Maybe a Defender layout on one side, Missile Command/Centipede on the other.
