I want to ask, should the two sentences from above be connected into one with a comma, or is leaving as two separate sentences?
Which is grammatically correct?
It's much better to leave them as two separate sentences.
then, how about the use of "so" to connect it? Or is it still better to leave it as two sentences?
You could connect the sentences with "so." I personally prefer shorter sentences, but if you prefer a compound sentence -- then go for it.
