I started my own test between BMiner and DSTM. I am using one 1070 on each miner.
Bminer is running on GPU0 and is reporting 470 - 475 Sol/s so i would say the average is around 472. Dev fee is on.
DSTM is running on GPU1 and is reporting an average of 452.3 Sol/s.
I will run this for 24 hours and then i will switch GPU's so that GPU0 runs DSTM and GPU1 runs BMiner, so the test will run for a total of 48 hours.
The reason for this is because GPU0 seems to run on slightly higher core clock even when OC is synced (i have identical cards). 
For now it looks like DSTM is in the lead.
If anyone is interested in results you can follow them here:

I will post an update after 24 and 48 hours.
