@Sing4me88 - Wave table synths are great for somethings but not for others, they can generate allsorts of contemporary sounds, which are not always what I need for a song.
If I had to buy just one synth again it would be the rather lack lustre sounding Arturia Pigments, it is rather special, it has both wave table and analogue technology, and these can be mixed together, honestly man, this is very special.
If you are thinking about Serum, and you either know about wavetable synthesis, or want to learn, then Pigments might be for you.
I particularly love the Filters, you get a choice of famous synth's filters, such as Mini Moog, SEM, Matrix12, plus loads more, and they are all very very good. There's a load of LFO options. And the sequencer is a dream, miles better than anything else I've seen and used.
https://www.arturia.com/products/analog-classics/pigments#enThe other synth I'm particularly fond of is an anal;ogue emulation of the Knifonium, by Plugin Alliance, I was looking for an OBX type growl and a while back I bought the Arturia OBX emuluation, but this Knif...by golly it has some depth to it, finding that I don't even bother with the OBX anymore, it does have it's place...
Hope this helps and I'd be interested to know what you go for, and I'd advise not to be influenced by the 'Most producers use it' argument.
(Now I think about it ...I seem to remember watching a Serum v Pigments YouTube...)
Hope this helps
