But just a minute. Wasn't the Gresley Pacific eclipsed by Pendennis Castle until it was modified to incorporate some of Churchward's ideas? And can someone remind where Holcroft was working when he sorted out the conjugated valve gear for Gresley? As for Stanier's origins, I don't think they were Crewe or Derby. Or Doncaster, come to that.
All true - undeniable. However...
The GWR from the outset had an advantage over the other railways - better coal, and a better graded railway for its expresses. The castles/kings did not have to use the poorer and less calorific coal that befell the Gresley Pacifics - hence the wide fireboxes to some degree, as opposed the much narrower swindon design.
The situation for all these railways - GWR, SR, LNER and LMS - were significantly different from each other in one way or another, hence their different developments. Yes, GWR men did some great things on other railways - in a similar vein, what Bulleid learned from Gresley in terms of "breaking the mould" was in turn to be used on the Southern Railway - and Stanier's designs for the LMS, undeniably Swindon in basic form, were further transformed from what could have been.
I don't think any comparison of the railways should be attempted at all - the differences in the traffic they carried, and how much, the routes they took, and the generally dismissive nature of consecutive governments to the railway companies, up until nationalisation, means that overall, any such comparison would be unfair.
Add to that - the wonder that is hindsight!
