Replacement hard headliners, whats best?

Got a pretty beat-up headliner so betting it won't be easily repairable, was wondering about replacement options. I see there's a hardboard one that comes in two pieces, which I'm thinking the join won't look original, and there's an ABS version, that I'm worried will warp and go funny on a hot day. What experience has anyone had out there with these headliners?
