Conclusion

tcpdf is actually not a good alternative. It's slow, the document is smallerbut do not includes background images, extra CSS and have a poor CSS compatibility(output is poor)
mpdf Can do a good Result, but with some html/css optimisation, this mean on a complex template, tweaking your layout in case of PDF output.
dompdf Have a better quality, but is the slowest, is a correct choice when you use it time to time. Especially if you cannot install wkhtmltopdf or want esay header and footer setup.
wkhtmltopdf Simply the best, the fastest but have to be installed(if you can) on your linux server and not only as a PHP class.
