One nice thing about Nicehash... ease of use, nice interface and BTC payout upfront - no waiting for confirmation of various coins BS etc.
The site you mentioned probably better matched for MRR but MRR is highly matured site with a very large customer base - me included. Hard to beat MRR in my opinion.
NH to earn their reputation again -- needs to come clean and pay everyone whatever that was stolen - that gesture itself I think will give them a chance to come back on top again. The sad part is that NH is one of kind and the demise would be a big loss to the mining community esp for newbies.
