I still have my SCPH-1180 (the Dual Analog controller that came out before the DualShock 1). I remember that Sony more or less rushed it to market in 1997 after the release of the N64 and the Saturn's analog NiGHTS pad. I was a bit disappointed at the time that it didn't come with rumble like the Japanese release of it did, but there were reports that the voltage from the rumble on Japan's Dual Analog fried people's consoles, so they left it out at the time. The DualShock 1 came out something like a year later, and when my first PS1 died, my new one came with a DS1.
The concave plastic-only analog sticks on the SCPH-1180 are not the most comfortable with circa-2017 hindsight in mind, but it having the longer handles than the PS1 digital pads and the DS1, 2, and 3 meant for me that the SCPH-1180 was the most comfortable version of a DualShock controller for me for ages until the DS4 finally came out. I would use it relentlessly with Symphony of the Night, FFVII, and pretty much anything else that didn't use rumble.
The dual flightstick, that I didn't have any experience with, but IIRC it came out about as early as the PS1 itself did. I'm sure that WarHawk was a good time with it.
