I personally prefer only test matches. Only LOI I watch are SL, and of course tournaments - WT20, ODI WC.
If time permits and a LOI is on I will watch a bit if I am not busy
Otherwise, my default is always test cricket - not just SL - all big series and whatever is being shown where I live that I can easily get on the tv.
I can't watch all sessions / every ball like back in the day but I watch a good 1.5-2 sessions worth of cricket when a big series is on.
I also don't follow any franchise cricket that closely other than a scorecard check. BBL, IPL, not for me. LPL only interested cuz its SL and try to watch what I can.
Watch test cricket whenever I can, that goes for tests involving any team. I watch shorter formats only when SL is playing, not to say I don't watch other countries playing but not that closely. Franchise cricket very rarely except for the LPL when ever I can.
