RTF vs HTML

Taking into consideration the types of Crystal Reports interpretations, Rich Text Format (RTF) and HyperText Markup Language (HTML), which option offers greater support and why?

I could see that Crystal Reports does not support :

<p style = "text-align: justify;"> ... </ p>

The text is not justified!

But after converting this code to RTF:

"{\\rtf1\\ansi\\ansicpg1252\\uc1\\htmautsp\\deff2{\\fonttbl{\\f0\\fcharset0 Times New Roman;}{\\f2\\fcharset0 Segoe UI;}}{\\colortbl\\red0\\green0\\blue0;\\red255\\green255\\blue255;}\\loch\\hich\\dbch\\pard\\plain\\ltrpar\\itap0{\\lang1033\\fs18\\f2\\cf0 \\cf0\\ql{\\f2 {\\ltrch ...}\\li0\\ri0\\sa0\\sb0\\fi0\\qj\\par}\r\n}\r\n}"

The text was justified perfectly!

Crystal Reports is best to RTF?

I'm using version 13.0.2000.0.
