I’d say better.
Kapil in his first full year in test cricket in 1979 at the age of 20, led the wicket taking charts in tests by a massive margin. He took 74 wickets @ 22.9 and scored 609 runs @ 30.9 in 17 tests.
In the subsequent year, in the Indian tour of Australia in 80/81, Australia were leading 1-0 and had to chase 143 to win in the third and final test in Melbourne. Kapil took 5-28 to bowl Australia out in the 4th innings for 83 for a historic win to seal a very unlikely series draw.
Kapil Dev had 75 wickets in 1983 @ 23.18 bowling as the sole test level bowler in his side for most of the time with only batting AR Ravi Shastri as his support. The second highest amount of wickets that year was 54 by Marshall. 11 of those 18 tests were against the ATG WI side against whom he took 46 wickets @ 20.89. The remaining 6 tests were against Pakistan which was the second best side at the time. He also scored 579 runs @ 22.26 to add to the above including a 100* out of 95 balls against a bowling attack of Marshall, Holding, Roberts and Garner at Port of Spain.
He did this despite also to this day having the most intense workload for a young fast bowler in test history along with the additional burden of batting. He has 247 wickets @ 27 under the age of 24. Nobody else is even close to that volume for at that age.
The below puts into context the bowling attack Kapil was working with in 1983:
