The fastest way to check blocks around player

Hi i want to check some blocks around player so what should i use?

$player->getChunk()->getBlockId();
or
$player->getLevel()->getBlockIdAt();

or any other way?

$player->getLevel()->getBlock()->getId(). It is the one that plugins are expected to use.
But for fastest, I guess $player->getChunk is fastest, although when the player is at margin areas of a chunk, you will need to fetch another chunk, which makes it slower.
