Adobe Scout, for starters. I'm not sure if you have ever researched its capabilities but it exceeds any other Profiler I've ever encountered by a mile. +Aleksandar Rodic
I'm not talking about which technology is better, either. I look at it from a distribution point of view. Web based standards are actually the worst way to get content to the end user. There is an enormous amount of fragmentation (browsers, slow adoption) that most developers simply don't have the patience for any more. The plugin/runtime model (Flash, AIR, Unity) is technologically superior in terms of quickly disseminating new features and runtime improvements. People have spent so many years staring into the browser that they forget that it's not the only way to consume interactive content.
This adoration for web standards was all about politics, but I am an engineer, I don't take sides based on politics. I take sides based on technical merit. I get it, you guys don't want Adobe technology running the entire web. But that doesn't change the fact that open standards have slowed us all down bigtime. I liken open standards to communism. Looks good on paper, but in practice is a complete disaster.
I much prefer having choice as an engineer in runtimes and development stacks. I know that with asm.js I can basically make WebGL content in any language I want, but it all goes back to the fragmented browser model. My opinion isn't a popular one, but I'm comfortable with it.
