This is a vast topic - rotational game breaks. Particularly 9 ball.
There's the discussion about how advantageous it really is. There's also the entire history of the 9 ball break, it's evolution and all the rules and changes made to alter the 9 ball break. (9 on the spot, break boxes, alternate break, anti-soft break requirements, rack devices, anti-pattern racking rules...so forth and so on) and combinations of those. There will always be better breakers and rack mechanics.
In the end, it doesn't matter because whatever applies to winner breaks applies to alternate break. Both are still breaks! The only difference is, the interruption caused by the alternating.
That is an excitement killer.
When you watch a player who is down in a match win a game, it's interesting to know they will break next as this would be a continuation of the streak or comeback. Control may surely change hands before that player evens up the score, but not always. It usually does though. But that's not the point. The point is - you DON'T KNOW. It could be in 1 game, or 5 games later that the table is handed over...AB totally kills that beauty. Same goes for the player who is tied up 5-5 and has the table, they could be in a journey to closing it out for the big win. You just don't know.
Instead, if it is the other player's break it's a big let down. An interruption. That "story line" comes to a halt. Now, it could continue on the following rack because the table is given back by the opponent say on dry break or miss...but it is spastic and broken up that way. It also kills player rhythm and if they are on a roll...
With AB you never get to see anything awesome. You are guaranteed to see a grinding back and forth most of the time. In WB, there's that rare chance the match you're watching may be some player's great 8-pack or something memorable.
As I said in my OP, it's a grinding battle. Euro's love it, because it matches their style. AB accommodates the more robotic, systematic, slow playing methodical styles. It's also very analogous to football (soccer). Once you get a lead, you hold it and run out the clock. Being very cautious.
That's what happens quite a bit in AB. Once a player is a few games ahead it is very hard to come back and win because your opponent will get the same amount of guaranteed opportunities at the table as the amount of games they have remaining to win. Very simply put, if it's 7-4 in a race to 9, the guy with 7 wins will get 2 more breaks guaranteed before the guy with 4 can even equalize the match or pull ahead. Now, breaks aren't sure things so players don't treat them as sure wins, but there is comfort in knowing that chance is there.
Now, please don't misunderstand me. I'm not whining about players who get behind in a match. That's their problem. They had equal chances to NOT be behind in the match, so that's tough cookies for them.
The point I'm trying to make is - the game changes in more ways that some realize. This leads to ugly, boring, s***style conservative play in end game phase. Less pressure play for one player.
It's much different to be up 7-4 on a guy when it is winner breaks, because knowing that you have no guaranteed innings later on if you give up the table means you must treat your current inning at the table as potentially your LAST.
This does in fact impact decision making. It is literally, a game changing factor.
