I too agree that most reviews out there are rather useless and more 'unboxing' style and banner spec repeating.
Both Mike & Dave do actual useful measurements or comparisons to other gear that is not just comparing numbers
(well, they actually
use the gear and show why they think something is weird/great/useful/novel).
It's a bit hard to put a finger on it but I think they do actually review the scopes differently and complement each other.
While Mike is more practical usefulness and of course tied to what he does professionally, Dave likes to take it apart and compares it to other gear he has used (or has in the lab).
It's not just about the datasheet values either but rather the curiosity to see what's inside and identify technology used in the gear.
I actually like the comparisons a lot since it is really difficult to ask a vendor for demo units.
Dave also shares his opinion on what he likes about it and what he thinks is useful or better or well done. Certainly able to dis a product too; or Mike's bug findings and usability/feature suggestions.
Point being that you get a broad overview of the scope by watching different style reviews and not just the one that identifies that it has too little memory
I've been looking forward to Dave getting the RTB2000.
Scope reviews are difficult. Compare a review done by Shahriar/Dave/Mike vs. e.g. Watt Circuit.
