Not to say that once the torpedo stopping the German it was very near France just at limit of Luftwaffe protection and the Force H would never had the lesser chance to arrive in time before the BISMARCK reached Brest safely. The only "jack pot" last chance the RN tried was the carrier aircrafts only ones fast enough to be capable to cross the distance. So, without this the BISMARCK escape surely and survive.
If you mean the following of the war and what would happen in the raider operation in south Atlantic considering the BISMARCK "condemned" by superior strengh of the RN , who knows ? It's only speculation. Fact that the BISMARCK mission early 41 wasn't the little GRAF SPEE or the MUSASHI 44 / YAMATO in 45 and was not a suicide mission.
Don't forget "the game" was not for Germans to start any battle of battleships with the Brits or superior forces but a race of chase and hide. The BISMARCK intact wouldn't have been easy to find in the large Atlantic and powerful enough to sink any RN warship to find her with chance or inferior ships.
Logical to think the German could get a secure place even forced to fight with arrogance to go through some trap and perhaps get back Germany by surprise at any time she likes by several possible ways (Remember the Adm. Cilliac fleet in the Channel with the SCHARNORST, GNEISENAU & tens of other destroyers. They forced the passage).
Well, if you mean the BISMARCK outgunned and overrated by propagandes, I agree with that. The BISMARCK in fact was a modern concept of classic WW 1 battleships and not really revolutionary . But just imagine the Denmark Strait combat started at distance of 18 km! (10 nautics). And at the third adjusted shoot, The HOOD was hitted and sunk! Not so bad the German gunners with a classic artillery... Would say "More than dangerous".
I think objectively the BISMARCK free, classic but new and faster than the Brits in Atlantic would've been a big disaster for the Allies for long time before they can to catch her ...(May be, not sure)
