Ethereum rollups deployment platforms in 2026

Trying to get a realistic picture of where rollup deployment is right now, not the hype version. I've been reading through documentation for most of the major platforms and the gap between what they promise and what teams actually experience seems pretty significant based on forum posts and Discord convos.

Specifically curious about a few things. How much does your framework choice actually constrain you after deployment? If you start on OP Stack and realize Arbitrum Orbit would've been better for your use case, how painful is that migration realistically?

Also the maintenance burden question. Every platform promises "one-click deployment" but what does post-launch actually look like for the infra team? Are you constantly babysitting the thing or does it run without much intervention?

Asking because I keep seeing projects underestimate this and then burn significant engineering time on infra that should be going to product. What's been everyone's experience?
