OTS guardian VS AGA from Interspiro ?

[Hoyden]

I have owned, worked in, and serviced both AGAs and Guardians. I greatly prefer the OTS - it is easier to doff because the buckle system on the AGA is suboptimal. I do like the ABV on the AGA better, but it does not outweigh the buckle system improvement on the Guardian.

YMMV.
