So are dedicated buffers better than built in ones?

I think they are the same--as part of a pedal or as standalone unit. I think a standalone unit just give you some more options for placement. You can use them a little more surgically that a pedal that has a built in buffer where placement is dictated perhaps by the main function of that pedal.

Take Cornish for instance. His pedals all have the same buffer in them as his standalone LD-1 and LD-3 buffer pedals.

 

I believe there are several buffer designs. Some may work better with your rig than others.

 

Here's a thought: Boss pedals have buffers. Boss Waza Craft pedals have a better buffer than their regular line of pedals. Is this the major difference between those two Boss lines of pedals?

 

I know that people generally tend to like the Boss buffer but the NS2 I have sucks a bit of tone when in the chain.

When I switched from the original Polytune to the V3 with the Bona Fide buffer built in, I immediately noticed a stronger and brighter signal.

 

Many pedals have a level pot on their output, so even if it's post-buffer, it may not be as low impedance as a dedicated buffer.

 

No, a buffer isn’t any different if it’s built into a pedal or on its own as long as it’s the same design (Cornish, fullton, analogman, etc offer both options).

My guess is that the buffers earlier in the chain are restoring your high end, not adding it, and you may like or just be used to the high end roll-off.

Since the xotic is at the end of that many pedals and cables, a ton of signal loss has already occurred and there’s little to no high end to restore so it sounds more neutral.

It most likely sounds “better” because it’s adding signal strength to get to the amp after all that capacitance build-up.

 

One of my favourite buffers is the one that's in the ARDX20.
