So I have a 2014 with under 9K miles on it, ever since the weather got warm I have noticed the smell when I step on the gas.

From what I have read it could be the cat converter.... I am just curious if this is normal or should I be worried.

It could also be the gas. Are you using a heavy ethanol blend, greater than 10%? If not, maybe there's a problem with one of the sensors. If it doesn't clear up soon I would take it in. It shouldn't smell like rotten eggs for an extended period of time.

It is most like because you drive at lower speeds it is a 2013 Rubicon with 11,000 miles and I seldom get mine above 50 mph and the jeep spends most of the time riding the logging roads of Northern Maine. On the rare occasions it is on tar and the hard top is off I get the same pleasurable smell that you are describing. It is normal and just the Catalytic Converter cleaning itself out. If you are not driving at slow speeds a lot and still get the smell then you may have an issue with it.
