Regarding a "perfect sound" there are many other elements that affect your sound, as you know, rather than compression.
My idea is that if compression is not used wisely, there is a general overuse of compression. A split-band compressor is great, however, both software and hardware solutions may help you, it simply depends on your budget.
Generally, I consider Behringer on the "lower" end of the hardware market and do not generally like them, however it all depends on your budget. I would recommend to you a software solution until you can afford something a little better.
Sincerely,
God
