I must say, I've been happy with PalmTreeNetwork for staking, seem the advertised staking rewards for most validators are higher than what you actually get.
At least with palm tree ive been getting 16%, with the other I've staked with its been 8-10% and thats with a lower fee. I guess they wont have a better APY until they are able to acquire some more nodes, wish I would have known this in the beginning, may have chosen differently. I plan to stay staked with these other providers until the initial weeks of MEX distribution are over then, I'll look for a different validator.
I believe in ELROND the project, just been disappointed in the difficulty in receiving rewards, when I 1st staked I was placed in the waiting period and bought a large bag of EGLD due to believing in the project and it offered at the time the 29% rewards. Never saw those rewards due to the demand for a delegation spot. In the long run glad to be invested in one of the most promising projects in blockchain.
Hopefully Legacy delegation will release some of their nodes so other validators/delegators can get a decent APY in the not to distant future. I believe also, PalmTreeNetwork released some of their nodes released freed up some of their nodes so other validators could utilize them, in the hopes that other Validators with a large node count in relation to their stake might do the same to give some balance. Doesn't look like that has happened quite yet. lol
