For ring game it comes down to a matter of preference I think.
You may be better sitting down at a table with a full stack and using that to your advantage or you may be better suited to buy in with the minimum and just wait for good hands. Short stacked forces you to play only "playable hands," which is good. However, short stacked people will get calls with weaker hands, and losing may just be part of it
One last thing, It is important to use Bankroll Management as well, so if you can't buy in to 25nl with the max, you probably shouldn't be playing there
