Ewww thats a tough one out of the box it will take some tinkering and adjustments to get them in the same league as the sleds your describing, not sure if they would ever be similar. Its actually completly different, the sound is differnt the low end TQ stretches your arms at every exit out of a turn, and its just as much fun. Can you absoutly rail through corners like some of those otehr sleds i'm not sure with my viper nobody could catch me in the woods that I ride with. I'm not superman I jsut had confidence in the sled and it did what I wanted it to do. My RX is different and once set up will give you the same confidence. If your not worried about top speed a phazer would be more similar to those sleds and everyone that i know that rides one just has perma grin from it and at the end of the day thats what its all about just having fun.
Long awnser for NO it wont be the same without some mods and attantion to detail in the adjustments.
