The method User::isBlocked() attempts to answer two questions: (1) Does the user have a block? (2) Is the user prevented from performing this action? The method can answer #1, but it cannot answer #2. Since User::getBlock() can also answer #1, this method is redundant. The method cannot answer #2 because there is not enough context in order to answer that question. If access is being checked against a Title object, all access checks can be performed with PermissionManager:userCan() which will also check the user's blocks. If performing all access checks is not desirable, using PermissionManager::isBlockedFrom() is also acceptable for only checking if the user is blocked. This method does *not* determine if the action is allowed, only that the user's block applies to that Title. If access is being checked without an existing Title, User::getBlock() can be used to get the user's block. Then Block::appliesToRight() can be used to determine if the block applies explicitly to a right (or returns null if it is unknown or false if explicitly allowed). If the user is creating a new Title, but the text of the title is not yet known (as in the case of Wikibase), access should be checked with Block::appliesToNamespace().
