Hi noguud!
Thank you for you comment.
In my opinion, "Vintage Overdrive" and "Sweet Baby Overdrive" are both fantastic pedals, but if you also consider the price, are really really great pedals!
"Vintage Overdrive" is amazing for rythm overdrive guitar. It has like a hi-pass filter, so the bass are light, not boomy, but highs are creammy combined with the natural overdrive form the amp.
"Sweet Baby Overdrive" has a mid-high crispy tone, but it preserves the bass. Also it responds very well to the dynamics so it's perfect for light overdrive solos with single coil pickups.
An external pedal gives a fat response, more natural attack and more sustain in comparation with the sim pedal. I have recorded a demo with the same adjustment controls in both pedals, Joyo and eleven Rack Sim. You can see what pedal I've used in the comments.

Maybe you couldn't note the difference because I've used a high gain amp sim, but it's clear with mid gain tones.

See you.
