My post was meant mischievously, I love my Speedlites and it's not really fair to compare them to what are basically portable studio lights. The same goes for Einsteins, I guess you would say we're comparing apples to oranges AND bananas! Each has their place. I do think that the 600EX-RT is the best small portable strobe system in it's class. Just my opinion, before every Yongnuo owner writes to tell me how wrong I am!
I've been impressed with what I've heard about the Paul Buff products, but have never used them. Probably due to the fact that they are only readily available in the US. As far as the Profoto's, the ETTL is not really a big factor in why I got them, it's a nice to have, not a need to have. More important was obtaining the lightest, most portable battery-powereed monolight I could get. The Einsteins with a separate battery and inverter aren't really the same thing, yes, they are cheaper but you always pay a premium for the smallest and lightest. I have a couple of freelance colleagues here in Dubai who get rental budgets for shoots and I recoup some of the cost by renting gear to them. The final deciding factor was the fact that they'll take all the Profoto modifiers which are also available worldwide.
It's all about the right tool for the job, as you say!
