I use Agoda primarily because they give and additional 4-7% back to you once you submit a review of the hotel I stayed at.

agoda gives you points which u can use for discounts but i have submitted reviews for every hotel i stay in but never got back the 4-7% back unless you are talking about the points. It's 500 additional points for a review.

Booking.com has a Genius program.

After booking with them for a couple of things using the same email, I get another a 10% discount on top of the smart deals discounts.

I think this is more than what Agoda is currently offering and you get it upfront, plus you pay only after you stay. Just don't book hotels that are "non-refundable". Those are more like pre-pay offers.

Try this hotel:
