I'm using a few mobile wallet apps like MetaMask, Trust, and SafePal, but MEW is still my favorite when it comes to interacting with ERC-20 tokens. Maybe because MEW only supports ERC-20 tokens, it maintains smoothness, while other wallets support multiple EVM and non-EVM chains at the same time, causing the user experience to be very negatively affected.
I agree that other wallets that support multichain are very convenient, but everything comes at the cost of complexity in the interface and user experience.
