I find that the undergraduate organic chemistry textbook that is being implemented in studying o-chem (1st and 2nd year) should reflect the study patterns as proposed by the lecturer. In this instance, Clayden and Greeves become somewhat redundant, since it is dissimilar to most units undertaken (especially here in NSW, Australia).
I have religiously used Wade and McMurry, the former is exceptional in explaining reactions mechanistically; however, it lacks severely in the spectroscopic side of things. McMurry was the prescribed and I used to look down on it, but when it came to exam revisions it was ok.
All three aforementioned books lack one major thing, they arent robust enough to carry out a 2 semester session in organic chemistry. If they are rich in the reactions and mechanisms they lack the spectroscopic definition. McMurry doesnt even come with a index table for common IR, H-HMR and C-NMR.
I would have to say that learning spectroscopy is best through lectures, my lecturer (Dr. Andrew Try) was exceptionally good in teaching us this, he actually made it fun. Pavia's spectroscopy is a good book to have, its cheap, straight to the point and relevant to undergraduate students.
I question the feasibility of having Vogel or March's, they cost a lot of money and are not of use to undergradaute students. They are only good for those who are doing postgraduate masters study, however even then it wont be used to a great extent. These a library books that should just be borrowed, it would be (in my opinion) senseless to purchase them, unless of course your prone to doing a lot of lab work.
The primary goal of an organic chemist varies depending on his/her speciality and therefore the books suggested, I believe are not relevant to people such as myself and indeed the authors mentioned superceded by newer more innovative writers that make learning o-chem easier.
