I've got the 270 Masahiro VC (carbon) and I like it a lot; I'm not a pro. Reputable folks say the MV (stainless) is good stuff for the money. Mono will be easy to maintain. It will be righty biased. Global Kitchen Japan has 15% off for the next day or so.
If you're willing to wait for a week or so, Amazon Japan ships for free Tojiro DP (also known as Fujitora)
VG10 core 270mm suji: https://www.amazon.com/TOJIRO-Co-Ltd-Production-FU-806/dp/B06WLNJ9ND
I've bought a couple of the Tojiro/Fujitora petties from Amazon Japan, no issues.
Another plus, is that it doesn't have the "Made in Japan" stamp that the US market versions have.
