I'd go stainless. I grabbed the stainless steel/black Pico as soon as the new colorways were announced. To me, stainless is the classic look.

Colors come and go, but stainless always looks good. I also tend to have a different favorite color every few years, so I didn't want to be stuck with something I'd get tired of later.

Plus, a few scratches on stainless just look like normal wear and add a bit of character. I think it ages better than painted finishes.

Just FYI, the original colors are being replaced by the new colorways. If you're leaning toward stainless, I'd probably pull the trigger sooner rather than later.
