I do not recommend playing with
https://zombiewager.com because they look suspicious, but you I give an approval for stake.com since it's very popular in the forum and it has a good reputation here. Just be careful when playing online, go with a more reputable gambling sites to protect your money.
Try to explore the forum in this section -

can people tell me there experiences with these
No experience with the first one but I have experience with stake and I can vouch they are reputable.
They have a lot of games to choose from and their withdrawal system is instant.
