There are good Weber carbs & there are great Weber carbs.
Never heared that they are junk.
I have heard the Italian made ones are better.
The better ones have a sealed shaft & are on bearings.
If you get good linkage, the adjustments are not needed too much, if you get cheesey linkage, they can come out of adjustment more easily.
There are major gains w/a side draft intake over a standard 4 BBL.
If you have a pretty lumpity lump camshaft w/a 4 bbl carbed engine, running side drafts will smooth out the idle a lot.
More torque everywhere in the RPM band.
If you seen how much camshaft duration the modern inline motorcycle 4's it would surprize you.
If a modern inline motorcycle inline 4 engine had just a single throttle body instead of 4, they would idle like crap & not make anywhere near the HP they do with individual TB's (throttle bodies)
