There are so many mech mods out there, make sure look into as many as you can, I feel like there are many more simple options than either of those. I prefer mechanical with a solid 650 tube over ones like the nemmy/Stingray. Less pieces/seams equal less voltage drop and personally, my nemmy has threading issues after taking a drop from 3 feet, my vanilla clone has much sturdier threads imo. There's no perfect mod really, just some simpler options I think.
