Guess it depends on what pack are you trying to build. All those cells are fine, quality wise. Feb have lower CDR ratings but if you keep the max current at 4-5A/cell they will work just fine and they are cheaper.

I don't have experience with linkdata, but Bak 6500 is an incredible cell. Don't forget about Molicel M65A.

thanks for the info.
would make a 11s3p battery, for Bafang m510.

Molicel is not available for another 2-3 months.

Then I would go with Bak/Linkdata instead of Feb.

I agree. For up to about 20A/cell continuous, bit higher for bursts, the Linkdata 65P and BAK 65E are the best 21700 choices for “when new” performance. We don’t have cycle life data for them yet but there isn’t going to be any big difference between them IMO.
