Really im addressing the people that have a system setup how they like it but still transition to tiramisu beacause its the new thing then they discover X Y and Z changes to how they like it.. so if your happy then for now stay where you are.... if you like to play and tinker then sure but otherwise...Except a much more clean environment than (coldboot) haxchi. As a developer you should know how hard it can be to support Haxchi while Mocha (and Tiramisu) just work. Best example: WUPServer. On Haxchi it's hacked into MCP, so good luck utilising WUPServer and MCP in parallel (want to check your own title info or even just some system setting while accessing the USB drive via libiosuhax? Forget it my friend, Haxchi can't do that).
So right now you might be right: An end user won't see a big difference between Haxchi And Tiramisu but time will change as sooner or later homebrews will drop Haxchi support (and even right now there are homebrews running better on Tiramisu than on Haxchi. NUSspli doesn't need to unmount USB/MLC all the time and as a result needs way less I/O queue flushes, translating in more smooth execution / less lag spikes for the end user, for example. Another example are new Tiramisu API calls: On Haxchi NUSspli exploits IOSU which might freeze the console. On Tiramisu it uses a simple API call with zero freeze risks instead).
