(Comparing them with T2 bombers)
SN has the highest damage bombs, MN has the second highest.
SN 2957 damage, MN 2850 damage, lowest of any nation is RN with 2563.
SN DBers are the slowest though, whereas MN one's are average in speed.
SN moves only 565, whereas MN moved at 570. The fastest T2 bomber is UK with 580.
(You can see that bombers that do less damage generally move faster to compensate)
All T2 bombers have either 150, 155 or 160 seconds of fuel. Both MN and SN have 155.
MN also has further sight range than SN (555 vs 544) and a tiny bit more health (139 vs 136).
SN pilots have the most bomber ability of any nation, and the SN DBs have more AP defense than MN (17 vs 16) which means they can be harder to shoot down. But even the best bomber isn't usually that hard to beat, although bombers with exceptional levels of ability can be surprising.
Overall, MN is slightly better with most of its aircraft stats, but when it comes to damage done SN can't be beat. Overall they're pretty equal, you just have to decide if you want the better bomber aircraft, or the better bombs.
