I think they both work pretty well. Don't usually have a choice about which, because the manifolds you have dictate which type of seal you'll use.

How to replace oil pan gasket for Toyota Camry 1995?

Changing the oil pan gasket on a 1995 or similar year Camry is realtively simple, but does require removal of the exhaust pipe. You will need a new oil pan gasket and a new exhaust pipe flange gasket. Put the car on ramps or jacks to access the undercarriage. Remove the exhaust pipe by removing the 3 nuts holding the exhaust pipe flange to the exhaust manifold. These nuts often rust and prior application of penetrating oil may be required to remove them without damage. Once the pipe is unbolted, work the exhaust system loose from the hanging brackets. In most cases the entire system does not have to be removed since there is enough room to remove the pan with only the front hangers removed. Drain the oil from the engine Remove the 10 mm bolts holding the pan to the block. Remove the old gasket material and scrape any remaining gasket from the block and pan. Install the new gasket. Forma-Gasket or a similar product may be used in small quantities to "glue" the new gasket in place and prevent shifting while the pan is reattached to the block. Reinsall the 10 mm bolts in a cross pattern to ensure the gasket is compressed evenly. Do not overtighten the bolts. Replace the pipe to flange gasket between the exhaust pipe and the exhaust manifold with a new part. Reattach the exhuast pipe to the hangers. Install the 3 bolts connecting the pipe flange to the exhaust manifold. Fill the engine with oil. Pray there are no leaks!
