GPS-21801 GNSS antenna

Just noticed the what I assume is new GPS-21801 antenna on the SparkFun web site. Just wondered if anybody has any experience with this over the TOP106 (and if it is more robust). Strangely this appears to be at a lower price point than the TOP106 but seems to be better quality?

I’m not sure if it is physically more robust (shatter-resistant, etc); but GPS-21801 was added to the catalog because it is more resistant to the elements (better seals and whatnot)…I’d lean toward purchasing it over the TOP106, especially if it’s going to be outdoors
