I've only had positive discussions about mine. The only off look I occasionally get is from someone in a jacked up other brand, which really doesn't matter. Personally, I think the Raptor is the best, most well rounded truck available on the market. It does everything I need to to, and does it with the interior space, capability, luxury and all an around aesthetic nothing else has. Their resale value doesn't stay high by chance - it's the market's way of confirming the same.
As an aside, they are also popular amongst many I know that have exotics and premium luxury cars. Nothing made by premium manufacturers even comes close in terms of capability and well roundedness, and they are unique in that regard. There are multiple articles written in the last year citing the research firm MaritzCX's finding that the F-150 (Raptor inclusive) was the number one vehicle purchased by individuals making between 200k and 500k a year. I'd say there are many worse stigma vehicles to own than a Raptor.
As stated by many others - none of these things matter at all. Mine's a daily driver amongst a number of interesting special interest cars because it does exactly what I want and need it to do. Those that know love it. Those that don't still appreciate its style. Those that don't like trucks or SUVs won't like it, or any other truck regardless of trim.
