You are asking "Which is the better LaTeX style?"
I would say we should not speak here of LaTeX style, in my opinion is is a general style of handling references to tables or figures in a book or thesis.
Because a thesis has to be true and unambiguous, it is important, that each table or figure in your document must be referenced at least once. Thus each table and figure gets his own number you have to reference to. (Referencing only "see table above" is not realy clear, if there are more than on tables above ... Referencing to only 15.3 could be a figure, a table or something else. Always add the kind of reference to be clear, like figure~15.3)
A good example for an unmistakable reference would be "figure 15.3" for the third figure in chapter 15 and "figure 15.2" for the second figure in chapter 15. With LaTeX you write figure~\ref{fig:label} to get a reference to the figure you labeled with \label{fig:label}.
If your reference has to point to a figure/table on the same page this reference is clear enouph. If your reference points to a figure/table two or more pages behind or before, you make it easy for the reader to find the referenced object with the reference see figure~\ref{fig:label} on \pageref{fig:label}. This will result for example in "see figure 15.3 on page 122".
Package varioref makes referencing easier, because you have only to write figure~\vref{fig:label} to get a proper reference in your document. If necceccary varioref adds by his own the pagenumber.
Package cleveref allows you to omit figure etc. You must only reference with \cref{fig:label} to get a complete reference in your document.
For more informations please have a look into the package documentations.
