Im asking the people that own and use them on a regular basis. Or anyone that has a preference. The sparky 2.0 or the Revo. Im going to buy one soon and the only difference on paper i can see is the low pass filter on the 433 modem and the brushed connections. Im also buying a oplink to use as rc. And maybe mess around with telemetry in the beginning but i have an osd that tells me everything i need to know. Also if anyone has pros or cons please comment below. I would love to hear what everyone thinks. Thank you for your time and energy. Happy skys!

IMO Revo pros are
- better (although older) gyro/acc sensor - less noise
- more connectivity (flexi-io port)
Regarding sparky, I wouldn't say there are any real pros at all - the brushed connections would be useful only if the board was a lot smaller. Doing brushed quad with that size of the board doesn't make sense.

Many fabs replace the LPF with a 0 ohm resistor because it is cheaper.
Sparky2 was never more than a niche controller and is getting harder to find. Revo has flooded the market and will still be around for a while.
IIRC, you can do brushed with any of them if you can do tiny soldering, but if you want brushed, you may want a smaller lighter board like mini Revo or Nano.
Revo comes in several flavors including mini-without-RF, mini-with-RF, missing-baro-and-mag, vertical or horizontal pins, Nano circuit in a Revo size board, etc.
Revo uses old (end of life) sensors where Sparky2 uses more modern sensors they are equivalent, but the old style might be just a little bit better (not noticable).
Revo allows you to do PWM input, but Sparky2 does not.
Sparky2 seems to come in 2 (maybe more) flavors, "perfect black board from a seller on ebay ($43)" and "no LPF, 10k resistor instead of 0 ohm in receiver power selection, solder blob must be removed to use RF, but cheaper ($32 an xt-xinte.com)"
The two boards that I know of that seem to be made perfectly are:
- from the final official runs of OpenPilot Nano for $30 shipped (USA)
https://sasquatchlabs.org/product/genuine-nano-flight-controller-w-case (sasquatchlabs.org web store has closed)
- from the final official runs of TauLabs Sparky2 for $43 shipped (world)

Thanks for the input guys, your opinions hold weight in my book.
