It's what you get used to. I'm used to x86 being "dst,src". It never bothered me that on the Motorola 68000 it went "src,dst" as, it was what it was. Intel defined it one way, Motorola another way [1]. My gripe with AT&T style (and it's called AT&T because K&R wrote their assembler that way) is that it uses sigils to mark registers (something I've never seen any other assembler do) and specifically broke with the manufacturer's mnemonics. Yes, I can see why they did it that way (a consistent format for assembly across multiple architectures) but I don't necessarily agree with it (Go's assembler has gone father by not even bothering with the register names the manufacturer uses). Almost forgot---another annoying aspect of AT&T is the use of "$" to designate an immediate value. Every assembler I used (prior to my exposure to Unix) used "#" for immediate value, and "$" for hexadecimal. But noooo, AT&T had to use "$" for immediate, and "0x" to designate hexadecimal and thus, I hit a brick wall each time I read code in AT&T format. [1] Also interesting to note---Intel is little endian, Motorola is bigendian.
