Looking for thoughts on XY and SM sealed

Seeing a lot of good conversations here and figured I’d pick some brains.

I bought some XY Evo ETBs, an XY Evo and Unified Minds booster box back in 2020 and they’re worth a considerable amount. I’m just getting into vending with my personal collection and I’m trying to weigh whether I should keep holding long term or flip for cheaper/more liquid modern sets and slabs.

Any thoughts or opinions just so I can see some different perspectives!
