If the OS can see all 4 drives, then the "RAID" isn't hardware RAID and

Anything done in hardware must be faster than in software, so if true raid
works correctly and is being recognized by the os, I think it's
preferable. Of course, if software raid is the only option, I have no
objections using it.
This is very much not true. "hardware" RAID is just software RAID moved
to an embedded CPU instead and generally a much less powerful one than
the one in the computer. The only possible benefit in the past was that
it offloaded the data transfer to multiple buses on the card. But that
really doesn't matter now since each drive has a SATA bus or even NVME
and the OS is easily capable of fully utilizing the bus capacity up to
the limit of the drive.
