Not sure why we gotta choose? I like em both in many different situations. They’re great hands to have on the button and I’d take either one. If they were off suit and I was facing a raise then forget about em!
Always consider these factors. Effective stack size? Reads on opponent? Your table image? Ranges of hands your opponents could have?
In holdem, which two cards are considered the better starting hand? A 5 suited or J Q suited?
The question is somewhat incorrect. In addition to two cards, many other factors must be taken into account. For example, the status of the tournament, your place and imide at the table, and so on. When playing one on one, A5 is preferable, because in case of a mismatch you have a high card. When the JJ or QQ pair is formed after the flop, you still have two more streets to see the ace. In the game at low limits in this situation, there are many who want to try their luck on the turn and river. Straight in case of A5 is more obvious in case of a sharp increase in the rate. The calculator gives 58 against 42 in favor of an ace when playing in the same suit.
I think that the advantage of one hand or another is very subjective. But I would choose A5s for three reasons: 1. when placing on the preflop, A5s has an advantage in equity. 2. Many people say that QJs has a better chance of collecting a street. This is true, but do not forget about the lower straight with an ACE. 3. Flash. QJs and A5s have equal chances to collect a flush, but with A5s we have a senior flush and we can't lose to the older flush. And with QJs, we give the stack to the senior flash not only with Ax, but also with Kx.
I'm not a fan of any ace rag hand. I tend to fold these a lot. Others seem to have luck with them, but it's never been my experience. It reminds me of when I first started on play money where I would get all excited if I got dealt an ace and would throw all in then be left fuming because the pot was won by a hand that didn't have an ace.
In the example above I would prefer the QJ though looking at the percentages it's clear my idea is flawed. I just like the look of it more.
