I don't really have a top five, but I'd say that anyone who has driven the New York (USN ebb1) would probably agree it's in there.  IMO, the NY is the best ebb and quite possibly the best bb in the game, pound for pound, and with a good crew on it.  Even at-level though, it can dish out a lot of pain very quickly and if you ignore it in your QV, you will regret it.

I think event opro2 is one of them, as the original one is a very good ship.

Tbh, NY has nice lasers but the lack of bulge is a buzz kill. 

Hyuga is great

1. RM Giulio Cesare (1914). Multiple good armament options, excellent speed. Extreme firepower. All around great ship to play. The only downside is its size, which makes it a fairly easy target, at least compared to the Ciao Duilio.

2. USN New York. Absolute blast to play and a devastating opponent in capable hands, even for BB6s and Baram (monster ship). However, that thing is slow, which is why the above ship wins out.

3. MN Le Havre. Reasonable speed and excellent firepower with quads. Poor spread knocks it down a bit though. A decent ship with alternative armament options too. Gun setup is a bit awkward (1 fore, 3 aft), but good traverse helps counter the problem.

4. IJN Shinano. One of the few EBBs (above EBB1 tier) with its own guns, the Shinano is a blast to play and an opponent to be feared. It gets put well ahead of many contemporaries due to its options and blockshotting goodness.

5. IJN Hyuga. Despite the awkward gun setup (2 fore, 4 aft), 12 16" shells that pretty much can't be bounced make a nightmare opponent for all AWs and a major threat for anyone else. And, just for good measure, you can load with with Mikasa guns and zip around at 45+ knots with CA reload - a blast to go into W@W with. This option allows it to inch out other high-powered ships in its tier like the Maryland and Bismarck '43.

Honorable mentions:

-IJN Mikasa: A fun ship to play, but the reload doesn't even come close to compensating for the tiny number of guns and poor shell damage. It has quite possibly the lowest firepower of any BB, but is indeed fun to play. And you get a special feeling whenever you somehow manage to sink a BB4+ with it.

-KM O-Project II (1942): While hardly different from its regular counterpart (slight speed boost, extra support slot), this ship is insane in the right hands due to its speed and tight spread - while maintaining solid range - and is notably different from most other KM ships in play style. It also has additional options, though I don't really consider the 16" Ns viable.

-RN Temeraire: It's the paint job. The ship is nothing spectacular, even having less supports than lower RN ships, but it plays decently looks great while doing so.

They are all crap and should be removed, the game was better when you had to level on a ship line and ebbs were limited to the few. I would have rather seen effort made to expand ship lines (poutting in a new line for each nation would give people a reason to level and play again, oh and remove ability to power level) than ebbs which are now a plauge on the game. You don't need to level in a cv or ss any more in fact you don't even need a cv bo with the pcv almost as effective as a cv6. And now it is hard to even know which ships are the greatest threat as there are many similar looking different tiered models. Yes this is a moan but it is all adding to the fail gb culture of the game digging the grave deeper and deeper. EU blood has put a band aid on but remember this happened because eu died.

Probably not the place for a rant so sorry.

Thermidor ... no other ebb in this game owned me so much ... supreme speed + better spread than Alsace + montana dmg ... ;]

Vanguard 46  in my Options , remember me on the Old Vanny with the RP 12Ls
