We were looking for HRS and hotels.com. You can always consider tripadvisor.com as an OTA as well, or simply set up your Google Business account.

Kind regards

Hi

this depends a little on who you want to sell to. Rather to business guests or leisure guests?

Booking.com works for both, HRS is stronger with business guests. 
If you want to work with discounts, Secret Escapes. For leisure guests, you can also work with TUI and DER. However, they require contingents. I don't know if that will work for you.
Then of course there's Check24, which is currently getting a bit stronger.

Best regards

If you can avoid it at any cost, steer clear of HRS. Every HRS booking means manual work as HRS still doesn’t properly push data to Channel Managers and therefore into Mews. (i.e. Credit Cards)

I would also stay clear of any of those “old school” contingent ones that block your availability and nothing might come of it. Plus, most of those also mean manually importing the reservations as most of them are not connected to CHM’s at all.
