Only if you you are seriously interested/planning on adding balanced capabilities. There is another thread topic dedicated to just that subject discussing why or when it makes sense for either option (SE vs. BAL).
Honestly, as an owner/operator of both an A3 and Jot 2. If you do not have an immediate need or, are only just “thinking” about balanced, I would say save the $200 and run with the A3. You are not loosing out on enough to justify the added cost for the Jot 2, without a specific need for balanced i/o. Or, you have the extra cash and don’t mind paying for the opportunity to experiment.
Anything else I would mention has already been expressed by @WaveTheory in his response to you already, and in his review of the Jot 2.
