Yes it was. Still is. I almost bought a FireWire card so I could use an iPod with Windows before the USB model came out. I also remember an old Dell laptop I had having a FW port.
When FW400 came out we were on USB1 which was stuck at 12mbps. It wasn’t designed for hard drives and such. It was for floppies, keyboards, mice, printers, barcode scanners, etc. Low bandwidth. Not that that stopped manufacturers.
FireWire just wasn’t popular on the PC side outside of video editing (and perhaps other specialized uses).
USB got far more useful with USB2, which went to 480mbps, but IIRC you couldn’t achieve that and it had tons of CPU overhead. FW could max out its bandwidth and had low CPU overhead by design despite having a lower theoretical max.
But it was over. USB2 was cheaper and FAR FAR more common. FW800 existed for those who needed more bandwidth. But for most people USB2 was plenty and they already had it.
Thunderbolt took over for FW, and as of USB4 the two are basically the same (relative to FW vs USB’s differences).
