Street Demon vs. QFT Slayer Series

Looking for a new carb for my 72 Satellite in the $350 range. The car will mostly be used for street duty, so drivability, reliability and easy of tuning is important.
Looking at a Street Demon vs. QFT Slayer Series.
Pros / cons for each?
(Also I'm not interested in rebuilding another carb at this point so I'm not looking for the merits of that option)

Have you considered the QF brawler carbs?

Not off hand. I dont see a difference between the brawler and slayer carbs. They are both 4150/4160 design with the same features. Same design, same price, lets just call them the same?
Back to the question-
In my opinion the big pro to the street demon is the small primaries large secondaries. Second to that is the plastic body, with the Carter fuel bowl arrangement (no spilling fuel when disassembling) third.
The big pro for the slayer is the modularity with other holley carbs like tuning, jets, power valves, nozzles, accelerator pumps also all the gaskets are easy to find. Second, I already have the linkage set up for a 4160. Third, I have not played with the carter style carbs much so I am really familiar wit how the holley design and they are easy to tune apart from annoyance of spilling fuel everywhere removing the bowls.
IMO if there were a QFT 4175 carb for sale, that would be my silver bullet.

There are two things that I’m not in love about on the Carter-ish Street Demon and that is:

They use Holley jets in the rear and there own jets (for the rods) up front.

You need to take off the carb from the intake and remove the bottom of the carb to access the jets.

Depends on what your doing. After owning and running both, the holleys and demons are great if you're futzing with it all the time trying to get the last little bit out of it, like at the track. I know when I had the holleys on it was always needing a bit of tweak whenever the weather changed up. Not what I want on a street car I drive 2-800 miles on a weekend. Now I run a 650 Street Demon and I don't have any of that. I did the tuning on the primary side to dial it in for my rig, secondary jetting was right on, and never need to touch it. Smooth from idle through 6500 and back, no fuss no muss. BTW use a 625 for 400 cubes and under, the 750 above that or you'll get a slight bog on the secondary transition you won't be able to tune out.
