Its actually all I have been buying though I warn you that up until the ADR rebalance, it was only for investors and not traders due to liquidity issues.
Once the rebalance happens at 1 to 4 ADRs, LNGLY is the closest thing to actually trading ASX.LNG. LNGLF is simply a trading format without any actual support or ability to get any dividends in the future should they occur.
On some days yes, but on other days no. It usually evens out to be the same, because the losses are usually higher too. The only thing is I have a position since May which means almost 5 months...wondering if it's worth it to ride it out a year to take advantage of taxes....otherwise I would have bought LNGLY. Might still consider it.
