Mate, Logic Pro is FULL of fantastic instruments. The EXS24 factory samples are outstanding and have you covered for all your organic instruments (as well as pads). The ES2 is quite a lovely synth as well. I'd recommend getting to know Logic's plugs prior to investing in 3rd party plugs.
However, if you insist on jumping right into some 3rd party plugs:
For free ones, look no further than TAL. This guy makes some absolutely incredible free synths that rival many paid ones.
For synths that cost $, I'd advise to use this forum's search engine as there are many threads discussing members' go-to synths.
Cheers.
Cheers mate, i have gone through literally all the type of pads n stuff on my logic and theyre just not that amazing, theyre good tho but im looking for more albino/massive sounds (more proffessional inaway, well imo)
Cheers tho ill look up TAL
You can make some pretty sweet pads by just filtering sampled sounds in weird ways. The EVOC 20 filters are just amazing for making pads and atmospheres. Check them out mate, else I'm quite satisfied with massive and es2 for all sorts of sounds :>
Yo cheers people, i took your advice lostnthesound and have expanded my self using es2 mainly and you can create some class stuff! bllesssed!
