I bought an aventon Cordoba when the had the deal with free sugino pista upgrade, thinking which is better between them.

Neither is better

Neither are particularly great cranks, but the Aventon Push is 144BCD vs the Sugino Pista which is 130BCD. Generally speaking, if you upgrade the chainring a 144BCD chainring is going to be higher quality (stiffer, rounder).

so then basically the aventon one is better then the suginos is what I'm understanding. Good thing it came with both sets lol.

Both are very low end cranks. The Sugino Pista is like Shimano making Tourney, yes it exists and yes a company that makes high quality items also makes that but don't equate that level with high quality it is far from it. You can find a good deal of great 144 chainrings which are high quality but you can also find some decent 130 chainrings as well. If you put say a Sugino Zen chainring on your Aventonton cranks you will still have cheap cranks and even if you put say a Sugino Cool Messenger chainring on the Pista crank same thing.

If you want high quality in 130 BCD go Cool Messenger (I know the rainbow bolts are silly but the cranks are cold forged like the 74s) or you can find road cranks that are even better and outfancy and material the Cools and just slap a nice 130 chainring on it. if you want high quality in 144 I would go Sugino 75 Direct Drive (tons of great options for external BBs or regular 75s for limited ISO square taper BBs) or Campy makes Record Pista stuff if you want that heritage and quality (but like square tapers) or you can go ScRAM Omnomnoms which everyone seems to ride these days.
