Looking for some advice on picking my sleep system. I'm considering the...

Zenbivy UL sleep system:
- ZB UL 25° Quilt
- ZB UL 25x72 Rectangular Pad
- ZB UL 25° Insulated Sheet
- ZB Regular Pillow

EE Nemo:
- EE Engima 10° Quilt
- Nemo Tensor Regular Wide (25") Pad
- Nemo Fillo Pillow

Differences between the two are (current Black Friday prices):
- 9 oz. (ZB heavier)
- $100 (ZB more expensive)
- 10° of warmth (ZB worse warmth rating)

The decision seems clear here with ZB being worse for weight, price, and warmth but I'm really concerned about comfort over most things. I'm a side sleeper and I don't usually sleep great while backpacking (but this will be my first time putting real money into my set up). I'm worried that the EE Nemo set up won't have the same comfort effect as the ZB since ZB has the cool clip system, the hood, and the lock-in pillow. Do you think those three features will make the ZB significantly better?

I'm really interested in paying what I have to do get the best sleep possible. If that requires an extra $100 plus 9 oz. (I'm already well under 10 lbs. with current set up), then I'm not too worried. Looking for any and all opinions, thank you!
