I like org, and I used it in the past (nowadays much less), and its table features are really impressive. In particular I love the possibility to turn Emacs into a full fledged spreadsheet combining org and calc. Nevertheless, I don't like very much the final LaTeX output of org tables (I don't know if it changed lately, but looking to your screenshot it doesn't seem to be so), for example the vertical bars are questionable, but of course in Emacs you can customize every detail and the content of of the table is more important of its aspect that can be easily adjusted.

The vertical lines are not default. But yes, everything can be easily configured. For example to use booktabs, you can use something like:

#+BEGIN_SRC emacs-lisp
(defun orgtbl-to-latex-booktabs (table params) "Convert the Orgtbl mode TABLE to LaTeX using booktabs package."
   (let* ((alignment (mapconcat (lambda (x) (if x "r" "l"))
                                org-table-last-alignment ""))
:tstart (concat "\\begin{tabular}{" alignment "}\n\\toprule")
            :tend "\\bottomrule\n\\end{tabular}"
            :lstart "" :lend " \\\\" :sep " & "
            :efmt "%s\\,(%s)" :hline "\\midrule")))
(orgtbl-to-generic table (org-combine-plists params2 params))))

 (eval-after-load "org-table"
      (setq orgtbl-radio-table-templates
         (delete-if (lambda (x) (equal (car x) 'latex-mode))

      (add-to-list 'orgtbl-radio-table-templates
'(latex-mode "% BEGIN RECEIVE ORGTBL %n\n% END RECEIVE ORGTBL %n\n\\begin{comment}\n#+ORGTBL: SEND %n orgtbl-to-latex-booktabs :splice nil :skip 0 :no-escape t\n| | |\n\\end{comment}\n")))) #+END_SRC

Then orgtbl-insert-radio-table, puts something like:

% BEGIN RECEIVE ORGTBL the-name-of-the-table
% END RECEIVE ORGTBL the-name-of-the-table
#+ORGTBL: SEND the-name-of-the-table orgtbl-to-latex-booktabs :splice nil :skip 0 :no-escape t
| | |

and a table like:

| A | B |
| a | b |
| 1 | 2 |

gets translated to:

A & B \\
a & b \\
1 & 2 \\
