I think back when that decision was made ARM servers were still believed to grow rather quickly.
So for Fujitsu going from SPARC to ARM might've been motivated by the expectation that by 2020 the ARM software ecosystem would be far superior for their purposes.
It doesn't hurt that ARM is willing to add SVE to the ISA whereas Oracle, Fujitsu and everyone else who uses SPARC are used to everyone doing something slightly different than the next guy.
Also maybe the CPU designers don't like register windows.
