Last time I checked, the M46 is a tank. And I don't recall when VFC made 1950s-era armored vehicles.
That said, it depends on how much the Inokatsu is. Being high-end biased, both would be good choices, but the Ino is just on another level. All of it is steel, and I've heard reports of Ino M60's running for 200k rounds with minimal issues (read up on ardrummer's log on Arnie's). If you could get that Ino around $1k, do it - there is no equal, and Inokatsu has long stopped production of their M60's so it's super rare as well.
