The table layout is fun overall, and the rules are a min/max paradise with all of the different gem placement options. The best description would be the layout feel from Elwin's Jurassic Park, with a heavy dose of the minor villain rules from Batman 66. The comic style playfield artwork looks amazing, although the display animation is primarily sliding/zooming stills of the characters like a digital comic. It doesn't look bad (Other than the bland trophy room background), but it does feel a bit lacking compared to what Stern put together for TMNT's animations with 3D modeling. Theme integration is spot on, following the comic version of the Marvel Infinity War.
There are definitely some minuses with the table layout. The outlanes are ridiculously hungry, with the somewhat higher placed slings often throwing a ball directly into an outlane with no real possibility of saves. The table has the outlane post adjustments in the easiest position by default, although the openings to the outlane still feel huge. Flipper fade from overheating coils can also be an issue depending on play style, which can prevent some ramp hits after a solid 30-45 minutes of play. Solvable with an after market cooling system, although concerning this is becoming a more frequent issue with Stern tables. Earlier Prem/LE runs also have problems with the Subway ball-walk mechanism breaking, the subway not dumping into the VUK correctly, spinning disc leveling issues, and playfield chipping from the Ant Man and Thor guides.
For Prem/LE specific features, the subway and lifting disc look neat, but it's all flash with very little practical function. Having played the Pro as well, I can say the subway mechanism doesn't really decrease the flow of the game, it just doesn't add much either. The Captain Marvel ramp is the biggest difference since it provides safer Ant Man and Captain Marvel shot returns. Unfortunately, ramp rejects are somewhat regular with shots that rattle out partway up the ramp or a hard clunk off of the leading edge of a rail wire. I've had a few shots escape toward the back of the table out the hole in the rail, as well. When the shot is on, though, it does feel great to hit that 180 vertical turn. There is a 3D printed clip-in part tdiddy created that makes a dramatic improvement with the ramp reliability which I strongly recommend for Prem/LE owners.
The table is fun to shoot, although the issues with the Captain Marvel ramp might make the Pro more attractive for moderately skilled players. I'd also not recommend this for someone's first table to own, unless they have very solid pinball skills or are really into Avengers/Marvel.
Post v1.0 code milestone:
With the latest updates, if you don't really care as much about scores and typically focus more on mode completion and progression, this is probably not a good table to own. I really don't care the direction Stern went with the rules, although I fall strongly into the mode/progression category. If min/maxing the score isn't a key focus, progress consists of collecting gems and repeatedly collecting the same set of Avengers. The game also forces a timed gem defense mode that ends in either losing a collected gem (And possibly a ball) or the gain of one gem.
