Top is the C-More STS (Small Tactical Sight). Has switch for brightness control (hi or lo) and on/off. Very clear well defined dot
Bottom is a JPoint, which at one was the same as the Trijicon IIRC (no guarantees on that). One brightness level and on/off controlled by removing cover. I've had issues with "dot flare" (dot not clearly defined) on mine.
Also had one of the original Burris Fast Fires. Wind/Elev adjustments broke after warranty expired.
FWIW,
