I went through all the popular tank choices a few months back and the sump/baffle was foremost on my mind.
The stock tank, as Jack shows above is actually a nice piece. Heavier gauge than aftermarket, with the proper crimps where the tank straps need to reside. The sump is a sound design but the production means of affixing it into place, not so much.
The tank "rednotch" shows in the linked Pro-M video is not a stock OEM tank. It is made in Canada (Montreal) by Spectra Premium. The gauge thickness is slightly less than the OEM tank.
I discussed the tank baffle with an engineer there. He wasn't aware of typical starvation issues with their design. It is indeed a bowl, fed by two ~7/16" holes in the bottom. Overall, the tank is a nice piece from the aftermarket.
Lastly, what may be the most popular aftermarket tank sold out there is made by ACP in Taiwan. These are typical of LRS, etc.
These come with a nice interior/exterior coating (the Spectra comes with nothing more than a slathering of oil, for example). They are thin gauge, with some minor crimp errors, and less than factory wide tank flanges in some spots. The baffle is the least desirable of the three, IMHO. It is literally a bowl with a single ~9/16" hole in the side of it.
