Since stoves are so light, its easy to pack them in. I don't like using a stove, when I'm moving camp every day or so; but if camped in one place, the stove can be great, even in September. I often get snow in September or even just down in the 30's. With a stove, a guy can be in the tent in just a shirt and be very comfortable. I've been using the same teepee and foldable stove since 2009 (neither still available to purchase). That's a lot of use for the money.
For spike camp, I still just use a tarp or only a bivy bag, if no rain. But "spike camp" has different meanings for different guys: I'll use the teepee and stove for base camp a few miles in from the truck, then spike out from there. Either way, quality pad and "bag" matter. If you don't have a bag dialed in, look into a quilt. For me, its more comfortable and much lighter.
