At this point cloud mining is pretty dismal in terms of returns. With decreasing BTC and providers trying to keep a profit at this time most cloud mining operations you can buy in low however it is uncertain if they will pull out of low returns anytime soon.
The best I heard so far is LTCGear (bitcointalk thread:
https://bitcointalk.org/index.php?topic=759743.0) decent ROI and as far as I am hearing the few that people are still pretty optimistic about. Give it some time to buy shares though (always sold out lol - can check
https://ltcgearcalc.com/ they have a good automated checker if things are in stock)
No referral needed just helping a fellow miner out =P lol
I have been testing multiple cloud mining services, to decide where I want to put major money.
So far I have looked at Zenminer, Zeushash, genesis-mining, ltcgear, and ihash-mining,
In my opinion the most professional service price goes to Zenminer - their interface is beautiful and easy to use. The prices are a little high but they are an innovative company - I say you put some money into them.
Other than service I also looked at payouts and ROI, and for that your best bet is iHash-Mining. They are a new company but they offer the best prices on the market due to their opening sale. Since they are new, I just bought their mining contract. I will see how that goes. Other than ihash-mining. LtcGear pays out well too; however they are always sold out and there site is hard to use.
All in all it is up to you where you put your money. If I were you I would try Zenminer and ihash-mining first.

I would not suggest ihash since its a total scam. This should clarify
