As something as they come

As something as they come
 

FreeDictionary gives
as something as they come as much of a particular characteristic as is possible
Eric is as competitive as they come and always trying to win.

What would be a good Spanish translation?

Eric es tan competitivo como se pueda ser y siempre intenta ganar.
Eric es (un tío) competitivo donde los haya y siempre va a por el triunfo.

Any other options?

How about ser tan______como el que más?

I'll go for that one, and the rest should be "...siempre tratando de ganar"

Thank you for the options. I probably take the same as Chileno, but the "tan ____ como el que más" is a good one, and idiomatic one too!
