I'm using Ethplorer to check my wallets and track my tokens if the token I waited coming from bounties have finally arrive in my wallets, I have so many shit tokens in my wallet that are sitting in my wallets for years but I notice that some coins do not have value in Ethplorer whereas in Etherscan they have value, did you also notice that, which of the two are you using to check your wallet.
I use etherscan for tracking my wallets. Although, I've used ethplorer couple of times but to be candid, etherscan is has more functionalities than ethplorer like you mention yourself, the price tracking of etherscan is really acurate and it cover quite a lot of different tokens. There other features etherscan is having over ethplorer
