In your opinion, is more comfortable investing in Genesis or Gaw? Genesis seems more legit.
Depends really, I like GAW Miners and I do like GM.
The Zen pool and the Hashlet Zen are paying out pretty well at the moment compared to their other products.
I would keep an eye on GM though as well, as they have X11 and even possibly, from what I have read on the web from Blog sites, X13 contracts as well coming soon.
So that would help perhaps with the BTC payouts each day as they have been going down and down, all of the pools, waflle pool, cleverpool etc etc are having lower payments.
The only one that does not seem to be affected is the Zenpool.
GM do offer a good deal with their 1 MH/s contract though, the payouts do seem lower at the moment compared to the zen, but the difference in satoshi every day is just a cent or two each day. The Zen has to eat almost 3 USD away (Zen costs 20.95 compared to 17.99 for GM) from those payouts before it can be a true beater and reach ROI first and so far it is only eaten away 26 cents, so a way to go yet.
Zen do have features coming soon for the Hashlets as well, which you will need Hashpoints for.
Anyway, they are just my thoughts.
