you don't pit a battlecruiser against a battleship as the battlecruiser will loose because of lack of armor in comparison to a battleship.
There is not mystery of unanimous experts point of view that therefore the 25 May when intact before the rudders (They were two) torpedo the BISMARCK sailed good speed to Spain in all security. No obstacle and even the RN lost her trace. This is the too proud Lütjen error radio message to Berlin to announce the HOOD sunk and this stupid long response of Berlin about his birthday whish permitting a radio goniometry and a boatplane confirm that re-localized were the German was. But RN ships, them, lost the BISMARCK totally. She changed route when the NORFOLK only one with a fixe rough radar tracking too close the battleship shelling the cruiser so hard that she turned back to lose the German definitely.
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)
Why should have Bismarck survived the battle, if she would still have had an intact rudder? She was still outgunned compared to the British battleships, German shooting was not really constantly at a high level (already in the late phase of the Battle of Denmark Strait it was very poor, it would have been likely poorer because of fatigue), there were still several other possibilities for the British to attack (i.e. not only the battleships)...
Bismarck was not a superior ship, which could have beaten all the deployed British ships single handed. She was a pretty average battleship, based mainly on ideas from the First World War.
