Strange water pressure problem
It sounds like a possibility that the valve may not be open completely, or a small debris plug. Make sure the valves under the sink are open completely. If no change, turn them off, disconnect them and look for an online water filter and make sure it is clean. If no filter, or it is clean, then check the faucet valve. Again disassemble the valve (handle assembly) and look for debris. 1 or both of these could be your issue. Do the same on the other faucet. If after these checks and cleanings, thing don't improve, then your shut off valve under the sink could be blocked with debris. Same check applies here except you need to make sure the water is shut off to the house first. Make sure all your joints you disconnect are tightened completely before restoring water.
