I'm about to purchase my first "real" bike but I need some help. Are the components on the Giant Seek 2 worth the extra $200 over the Seek 3?

Shifters: Shimano M310 vs SRAM Via Centro
Front Derailleur: Shimano M191 vs SRAM Via Centro
Rear Derailleur: Shimano M280 vs SRAM Via Centro
Brakes: Tektro MD-M300 Mechanical Disc vs Shimano M355 Hydraulic Disc
Cassette: Shimano HG-41, 11-32, 8-Speed vs SRAM PG1030, 11-36, 10-Speed
Crankset: SR Suntour CW13- NEX, 28/38/48 vs SRAM Via Centro, 32/48
Bottom Bracket: Cartridge vs SRAM Power-Spline

I'm not familiar with SRAM and would appreciate any input. I just want to make sure I'm making an informed decision.

P.S. I'll be using this bike for fitness purposes on a established scenic bike path with some light off road stuff.
