Both are starter markers and will perform about the same. The victor is lighter and is more "speedball" styled. The 98 is more durable and more "milsim" styled.
No. There are better, higher quality guns in the same price range. Azodin, tippmann and the Spyder mr series would be better.
Tippmann 98, very durable and easy to fix.
The agressor is sold as a higher model than the victor.
The sonix, because it has an actual hand grip.
No, The Electra is Spyders "step up" from the victor. It is inside the same as the victor, but also has electronics and other features. The same with Tippmann, Azodin, and many other companies, they release a low, mid and "high" end gun together. The victor in this case is their cheapest and most "bare boned", then the Sonix, and then the Electra.
Tippmann 98's, spyder mr1/victor, and azodin ats/kaos are good to start.
they are the same design so i would say whichever is cheaper
The spyder victor is a more reliable gun than the JT. You should also look into the Azodin Kaos.
The Gryphon has nicer features, like an asa on the grip. However if you plan on playing for more than a few months, you should buy a marker at least in the 100 dollar range if you want it to last.
Almost all of them. You need to be much more specific in what you mean by "better" and ask a less open ended question.
There are no stocks that fit that model spyder.
