Suggest do whatever works best for you and your vehicle and its purpose. Suggest buy a good quality snorkel from wherever you can get a good price for a respected design and brand.
There are many, many snorkels adorning 4WD vehicles in Australia, especially Land Cruiser variants.
Selection depends on the purpose of the vehicle.
Those who want to avoid drowning an engine midstream in an accidental or deliberate deepwater crossing are fastidious about airtight connections through to the airbox/aircleaner/air intake. Airtight because that also means watertight.
Some folks are improving air induction to the engine with large diameter snorkels such as the impressive 4 inch Safari ARMAX unit – although this requires a lot of work to fit properly.
Be wary about claims of the advantages of the so-called intake air ram effect -- it is tiny compared to the draw (suction) of a hungry engine. However, larger pipe sizes -- intake and exhaust -- mean less flow resistance.
Others also are very particular about avoiding engine-destroying dust ingestion and add a precleaner at the top of the tube at cabin roof height --

This means a proper precleaner unit, not simply some kind of “sock” with or without oil impregnation. The "socks" and similar filters have very mixed reviews. “Dusting” has become a recent concern at the lid on the rectangular airbox on some newer Land Cruisers, most notably 200 series turbodiesel engines and for which careful sealing is a big deal. The lid on the round airbox on the 1HD-FTE engine seems to seal better – presume 2UZ-FE is similar -- but it is still worthwhile to check.
There is plenty of fitting guidance on Youtube as well as the instructions for “Safari” associated with ARB and the “Airtec” snorkels associated with TJM, plus snorkels from other reputable suppliers in USA. Toyota OEM snorkels often are seen in Australia on some commercial Land Cruiser variants but are not common as after-market choices. Be wary of low quality fakes and note the comment by

Removing or replacing a fender to fit a snorkel is very rare except for some specialised upgrades of air intake systems. Most people find that the fitting instructions for quality snorkels come with stick-on templates which are sufficient to help position drill-holes and cut-outs without mistakes. Golden Rule:
“Measure and check twice (maybe three times!), drill and cut once”. A Right Hand Drive example of fitting instructions for 100 series is attached – not sure if there are any differences for Left Hand Drive.
This 200 series video shows good technique around the fender but there are obvious differences to 100 series, especially around the airbox.
