Yes they're different.

• era-solidity-compiler: is the default zksolc compiler to be used by majority of projects. It generates the bytecode compatible with zkSync ZKEVM.
• era-solidity: a customised version of the solidity compiler to address some of the limitations identified when compiling projects with just zksolc. For example if your project uses Solidity 0.7.x and recursion (one of the limitations) you'd need to use both.
