I would go for Genesis Mining. Other platforms that are worth comparing are Hashflare, ViaBTC and Hashing24. Note that if you believe the Bitcoin price will continue to rise as in 2017, cloud mining is probably not a good investment compare to Bitcoin.
If you believe the price will decrease or stabilize cloud mining can be a good investment.
