Vent: My oak table finish cracked after using a water-based topcoat.
Oil-based poly is the only way to go for durable furniture.

But have you seen how much water-based finishes have gotten better lately? I put one on my oak desk years ago and it's still perfect, no cracks at all. I wanted something that dried fast without the awful smell. Oil based poly is strong but it yellows over time and the fumes are really bad. Maybe the cracking happened from putting on too thick of a coat or not sealing the wood right first. So it might not be that water based is always bad, just that it needs careful use.

Have you ever had a bad experience with water-based finish that made you doubt it? I used to only use oil-based poly for everything because I had a water-based one crack on me once. But @gibson.morgan's point about thin coats and sealing first made me see I probably did it wrong back then. So I tried water-based again on a bookshelf, used light layers, and it's been solid for months with no yellowing.

Wasn't oil-based yellowing always the trade-off though?

My mom's old dining table has that classic yellow oil-based look... it's warm but you can tell it's aged. I see this same debate everywhere now, like with phone cases or car wax. People get burned by a new thing once and swear off it forever, even when the instructions or the formula itself changes. It's easier to just say "the old way is the only right way" instead of admitting the process might need more care. We want things to be simple, good or bad, but most stuff just needs you to read the fine print.
