I'm a 4ch fan boi, but if you have integrated LA channels, the need for more than 2ch is significantly diminished IME, although it does depend what you're using it for of course (eg, if you're rolling your own SMPS). With that in mind, the Analogue Discovery remains a worthy contender if bandwidth isn't a blocker, especially for microcontroller development. I wouldn't be without mine. I have three of them!
