2011, 2017 & 2019, years when Tron, GoG and Sth were made, respectively. So we're not really comparing the same things just based on newer games having new tricks up their sleeves. But each game definitely has something unique to offer.

I would mention PRO in your poll choices since you want to compare PROs, for example, myself I wouldn't pick Sth PRO to be in my collection unless it's at least a Premium..

Edited: I mean, who would change their vote if they were told they can only have the PRO version?

I own a loaded Tron Pro and it's bolted to the floor.

My opinions here - I've played all games, myself would pick Sth over GoG. Again, only if it's a premium - you need those projections, they add so much to the immersion. That and the UV kit.

About having a game in a collection, do you see Tron in the wild that much? It's because they live happily in some homes! The music, the theme, the fact Tron is one of those heavily modded games out there. Anyone that plays it, it's instant fun! Not a difficult game to shoot, very satisfying shots. If they were to vault this, I'd be lined up already, and I would keep the original one.

My picks would be Tron, Sth (premium) then GoG (premium) in that order.

Why surprised? Stranger Things is more recent, Netflix series is still active (Season 4 coming), Tron is currently a thing of the past.

Many recent members have never played it, yet, it's still solid and obviously has kept its value and then some. I'm actually surprised it's taking in that many votes!

Two great games in any lineup, IMO.

No doubt, the code updates had a huge impact with Sth.

Tron's LE value skyrocketed recently, has it became some sort of 'prestige' game. Tron PRO followed with some price increase.

What RobT said, Tron PRO is 8 years apart from Sth Premium, yet it's pretty much the same value. I would say a highly moded Tron PRO may even fetch higher. Playing wise, not the same experience at all. I have fun when playing Tron, I'm just sailing along listening to the music. I'm way more intense playing Sth, animations are great, music and sounds are real immersive.
