Victron 100/50 and 2S.
It's funny the reason I went with these panels was their size. But I didn't compare them to other 200w panels to notice they were smaller.
That size is somewhat of a standard. I have some very old Kyocera panels that size that are 135W nominal and produce significantly less than that now. 165 W in the same size would be an improvement.
If you look at the spec sheet, the voltage required for maximum power is quite high, about 21V vs about 17.5 V for most other panels. If you don't have a good MPPT controller, you won't get full power, and if they are in parallel with panels with a lower maximum power voltage, they will also underperform. The efficiency loss with a PWM controller is also larger than for most other panels. From my calculations, they would only produce about 125W with a PWM controller charging a battery at 13V.
