There is no 'best' method to do deinterlacing or ivtc every source.
To convert properly 29.97 (30000/1001) telecined content to 23.976 (24000/1001) progressive frames any filter that does IVTC should work fine.
Problem is one often encounters content that isn't properly telecined, you often encounter mixed content, content with pattern shifting etc.
In general I would recommand to look at the preview and try:
1. TIVTC
2. VIVTC
3. QTGMC in bob-mode + sRestore
if none of these work directly you can try to tweak these methods and see if one of them helps or bob your content and live witht he dublicates, or use another tool.
There are a few tools designed for 'funky' ivtc decimation like Wobbly (https://github.com/dubhater/Wobbly), Yatta (https://github.com/hatt/Yatta) , AnimeIVTC, pvsfunc (https://github.com/rlaphoenix/pvsfunc) and there are also some scripts and code snippets some users use.
All in all there is no magic tool which automatically produces the best results.
Test way to IVTC content is to read up on what it is one wants to do, properly analyse the source (looking at field and bobbed frame to detect patterns and problems with the source), then decide whether one of the methods mentioned can help, whether one needs to combine some of them or whether some custom written methods are needed.
