Vaughan loved beating the West Indies in particular, while Strauss captained England in a series on absolutely flat tracks and was barely culpable for the one defeat against West Indies when England collapsed for 51. I have excluded the abandoned Test, I have no idea why that is even kept in the records since so little actually happened it simply doesn't make any sense.
Both captains beat Australia 2-1 in a home series, the only other significant series win for Vaughan was over South Africa in South Africa which Strauss very nearly matched but was denied at the death.
Overall Vaughan may have the better win percentage, but most of that is made up of strolls in the park against West Indies - more than 3/4 of his overall wins came against West Indies (10), New Zealand (6) and Bangladesh (4). Strauss on the other hand has a very good record against the better sides, and if he ever plays lots of four match home Tests against West Indies I'm sure he'll be right up there with Vaughan against them too.
Vaughan also had the massive advantage of Flintoff who scored 402 runs and took 24 wickets in the 2005 Ashes, compared to his contribution of 200 runs and eight wickets in 2009. He also had an arguably series winning contribution from a certain Simon Jones in both South Africa (15 wickets) and against the aussies (18 wickets in 3.5 Tests)
The one other stat I will throw in is regards winning when in front vs winning from behind :
1st Innings Leads/Deficits
Vaughan
100+ lead : P18 W15 D3 L0
1-99 lead : P11 W7 D3 L1
1-99 deficit : P9 W3 D3 L3
100+ deficit : P13 W1 D5 L7
So 22 of Vaughan's 26 wins came from in front at half-time, his win from 100+ runs behind was against New Zealand, the two medium sized deficits turned around against New Zealand and West Indies, and he turned around an EIGHT run lead against South Africa. Vaughan did lose when in front against Sri Lanka, a 93 run lead.
Strauss
100+ lead : P13 W10 D3 L0
1-99 lead : P2 W0 D2 L0
1-99 deficit : P5 W1 D2 L2
100+ deficit : P5 W1 D2 L2
Strauss has never lost when in front, his only four defeats coming when the side trailed by more than 50 runs on 1st innings - including the most recent defeat against Pakistan. His side turned around a 23 run deficit against Pakistan in 2006, the only other 'win' from behind with Strauss in charge was one I won't go into but let's just say it was in 2006 and controversial.
While the stats can be achieved as a result of the strength of the side, you can't persuade me that the players at Strauss' disposal are way better than those at the disposal of Vaughan.
So the question is, will Strauss be a better captain than Vaughan or is he already? In my view Vaughan was never all that good anyway, the wins against the weaker sides and a couple of good series wins against good opposition making up his reputation. Vaughan never beat Sri Lanka, Pakistan or India in a Test match let alone series, Strauss has yet to captain against Sri Lanka or India so maybe when he does it will be clearer. It makes me cringe whenever anyone tries to make out Vaughan as being as good a captain as Brearley, who never played rubbish sides and while he never captained against the West Indies so never faced the ultimate test, none of the sides he did captain against were poor and he didn't rely on whipping the whipping boys to gain his reputation..............................
