CRM is not limited to heavies - it fully exists in the fighter world, you're just working with guys in another jet (single seat world). Flight hours are less overall, but flight hours are also not "equal" either...1 hr in a C-17 is not a direct comparison to 1 hr in a F-16; there's a reason fighter guys are getting hired by airlines at the bare minimum requirements, so I wouldn't personally be extremely concerned with "total hours" if airlines are eventually your desire.
The guard fighters GENERALLY do 2-3 month deployments, unlike AD's 6 month standard. QOL in good; the flying/mission is phenomenal - do you want to fly at 100' AGL and 50K in the same sortie, blow assholes up, shoot missiles, fly in all corners of the world, go on awesome TDYs, etc? It's a great lifetstyle, but not for all...it's competitive, can be more stressful (good and bad), etc. If you enjoyed sports in high school/college, the camaraderie and competition, then you'll probably like it. If you though those guys were assholes and don't feel comfortable with competition amongst your peers, or think being 33 yrs old and still studying for several hours on a day you're not flying is bullshit, then it may not be for you.
