Bumrah and Shami are really good in Tests and ODIs while Ishant has been good in tests for last 2-3 seasons but other than that the bench strength is mediocre.
Bhuveneshwar who is considered a top Indian bowler in white ball cricket averages 34.60 while Umesh who is part of the bench strength is pretty average as well.
I havent seen a lot of young pacers as well currently to get really excited about. Saini, Khaleel have not left much impact while Deepak Chahar who can be decent with new ball, is mediocre with old ball. Tyagi, Nagarkot, Mavi are quite far from international cricket by the looks of it and not sure how they will develop.
For Pakistan in tests Abbas has been really good in UAE, Eng and Pakistan and averages 20 after 18 matches with bowl, Shaheen is also growing pretty well in tests and currently averages 27. In ODIs Amir is ranked 7th and Shaheen has a tremendous record for his age along with some records already. Pakistan also has much better bench strength in my opinion and some young prospects to look forward to that have actually created some impact in international cricket.
So while Bumrah and Shami are top class bowlers, other than them there arent many which can be called top class and form rather an ordinary bench strength at the moment.
If we talk about starting pacers in tests, India is ahead at the moment as Pak's pace bowling is really inexperienced. In ODIs its a close call, India does have more experience and pacer have consistent performances behind them but Shaheen has really stood up and bench strength of Pak is also decent along with Amir leading the attack who has tremendous economy and can rise upto occasion.
