Can I just talk about how awesome the Stanstead airport is from a railway perspective is. Like it isn't amongst the best served or best connected or anything but considering its size and location, it just tries so well.
It has trains at least every half an hour, if not every 15 minutes at certain times while the Gatwick Express is less frequent. It also has connections to other actual major UK cities, where Gatwick just goes to London and Brighton and Heathrow has no train service West so it is stuck with London while from Stansted you can get to Norwich, Peterborough, Cambridge, Leicester and Birmingham on top of London itself. (before you say anything, I know you can get from Reading and Guildford to Gatwick but like does anyone actually like that service, plus those places are in the small leagues compared to Brighton).
Considering that Stanstead is so much smaller than both Gatwick and Heathrow I would say it has an excellent service.
