Great question Joe,
Let me give you a different perspective..
I've had one of each and now have the 1998 GTS. I choose the GTS over the sold RT/10 because to be honest, I found myself with the Top ON 90% of the time. I loved the wind in my hair, etc, but everytime the weather changed I had to drive home and get the hardtop or waste time putting the soft top on. And when it did rain, it leaked like a wet sock.
I LOVE stereo's and with an RT/10,there was Hardly ANY options to have a nice sounding stereo. With a GTS, I have a place for a sub enclosure, rear speakers, and fronts for some NICE seperation and some SERIOUS thumping..
The GTS also offered quick access rear shelf for a odds and ends and the rear pop up glass was more convenient than the truck.
But.. I must say.. I sure loved my RT/10 though.. It just depends on your driving conditions, etc and what you want the car for. The GTS is more of an everyday vehicle and the RT/10 you'll have to check the weather at every turn, etc. I can't tell you HOW MANY times I've cruised w/ my Viper friends and they had to go home because of the top issue or couldn't go out because they didn't want to deal w/ weather, etc.hehe, Just ask Chuck, or Adam or Antonio.. RT/10's look sinister though!!!
Either choice, can't go wrong..
