While writing C code for ARM, I would prefer if() else if() or switch command. The while(true) + if() would add extra condition checking and would be slower.
How will it add an extra condition? The compiler is smart enough to understand while( true ) is an unconditional loop and will not generate the code for a condition check instead it'll just put a JMP instruction back to the start of the block. So no overheads there.
