if you really wanna buy a good synth, then imho id probably buy serum, cause you can draw/import/customize your wavetables to emulate pretty much any synth + signal path youd like and incorporate that onto the waveform itself. theres even (for example) jd-800 waveforms avaliable online and serum lets you import these, customize them, and make them to your liking; while also sounding great in the proces. that is really amazing to me, so to answer your question i would recommend serum
