I normally hunt with no shelter (just an emergency tyvek sheet I can throw over top of me if weather is really bad).
With that being said, I have used Western Mountaineering sleeping bags since the late 90's. The quality of the down, quality of the stitching and face fabrics, and weight to warmth ratio can't really be beat in my experience. The are also a continuous baffle design, meaning you can push/squeeze the down into areas where you might be colder. They also have what's called a semi-rec cut shape... As a side/stomach sleeper, I cannot use normal "mummy" style backpacking sleeping bags.
For sleeping pads I've had really good luck with quality and durability of ThermaRest. I used to just accept the fact that I was going to need a new pad every 6-12 months. I now carry the same pad year round no matter the temps. Coming up on around 600ish nights on my ThermaRest NeoAir XTherm NXT Max, zero issues other than it's a noisy pad.
Pillow is where people get really picky. I grew up packing in just a sweatshirt or beanie as a pillow, now a days I like a nice pillow, it really helps me sleep through the night. I use the Nemo Fillo pillow. It has a memory foam layer and then you can blow it up to desired thickness. It packs down smaller than a nalgene in its stuff sack, and the memory foam by itself can be a pillow if for some reason it punctures and loses air.
