My HMR wears a vintage (Japanese) Bushnell Banner 6-18 AO. Picked it up for about $175 in mint condition, and literally hundreds of gophers have fallen as a result.
My first pick? Nope, but I've had a number of these old, glossy Banners and they're great for use on rimfires. Probably great for other stuff too, but that's all I use them for. No need to upgrade when it's doing it's job so well.
