Remember to consider ESTA when you're looking at those huge-seeming reach numbers. The steeper seat angle will reduce effective top tube so sometimes those big reach numbers don't always mean a bigger bike, just a shift of the rider forward on the bike.
In relation to this, I've found ETT to be a very relevant number to inform me of how bikes with very different reach numbers actually fit in real life.
However ETT, similar to ESTA, is only an effective measure if you're of average-ish heights and proportions
