TBI vs Vortec Block

Hey Everyone! I have been looking at a bunch of different late model SBC 350 Gen 1 blocks lately and was wondering what the difference is between them in quality like core shift, power handling, and over all strength. When I refer to "late model" I am talking about 87'-up 1piece rear main seal blocks.

I know all late model blocks come with the option of a roller cam so both have the anchor points for the spider retainer. From what I have noticed cars got roller cams but trucks received flat tappet cams till the introduction of the vortec motor. I have also noticed that "880" or vortec blocks do not have the fuel pump pushrod hole drilled where the TBI blocks do. Are there any other things different between these blocks? Which one will hold more power etc...... Thanks in advance everyone!!!!
