They are the same Starting and Running watts and the same voltage (120/240).

A generator capable of supplying 30amps will be considerably larger than one capable of only 20 amps.
20A x 240V = 4800 watts, approximately 10 horsepower engine.
30A x 240V = 7200 watts, approximately 14 horsepower engine.
If both generators you are looking at have the same operating and surge wattage ratings, the difference is simply in the circuit breakers. Some manufacturers will over rate the protection to prevent nuisance trips.

With the 30 amp generator you will have 50% more power. We just purchased/installed a back-up generator since we moved to an area that has frequent power outages. It comes on every WED to test the system for 15 minutes, and we feel assured that during an outage we are taken care off for several days.
We have 5 tanks with tropical fish and would not want to lose them.

with a 30 amp, you can run more items. but be careful, have to look for the starting amps on the appliances. a fridge and/or freezer start at high amps for a split-second to get the unit running then drops to the running amps.

30 amp should carry more. in my perfect world , my generator runs a window unit, & freezer / refrig while it is on!

volts times amps equals watts .bigger
is more expensive. Depends on what you need it for do you have electric heat.

The voltage may be different.
